The diameter of a circular park is 63 m. Find the cost of fencing it at 7 per meter.

Answer:_______________

The diameter of a circular park is 42 m. Find the cost of fencing it at 7 per meter.

Answer: 924

SOLUTION 1 :

Given,

Diameter of the wheel = 42m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 42⁶

= 22 x 6

= 132 m.

Cost of fencing for one meter = 7

Cost of fencing for 132 meters = 132 x 7 = 924

Hence, the cost of fencing the circular park is 924.

The diameter of a circular park is 91 m. Find the cost of fencing it at 8 per meter.

Answer: 2288

SOLUTION 1 :

Given,

Diameter of the wheel = 91m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 91¹³

= 22 x 13

= 286 m.

Cost of fencing for one meter = 8

Cost of fencing for 286 meters = 286 x 8 = 2288

Hence, the cost of fencing the circular park is 2288.

The diameter of a circular park is 119 m. Find the cost of fencing it at 5 per meter.

Answer: 1870

SOLUTION 1 :

Given,

Diameter of the wheel = 119m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~119~~¹⁷

= 22 x 17

= 374 m.

Cost of fencing for one meter = 5

Cost of fencing for 374 meters = 374 x 5 = 1870

Hence, the cost of fencing the circular park is 1870.

The diameter of a circular park is 133 m. Find the cost of fencing it at 8 per meter.

Answer: 3344

SOLUTION 1 :

Given,

Diameter of the wheel = 133m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~133~~¹⁹

= 22 x 19

= 418 m.

Cost of fencing for one meter = 8

Cost of fencing for 418 meters = 418 x 8 = 3344

Hence, the cost of fencing the circular park is 3344.

The diameter of a circular park is 112 m. Find the cost of fencing it at 7 per meter.

Answer: 2464

SOLUTION 1 :

Given,

Diameter of the wheel = 112m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~112~~¹⁶

= 22 x 16

= 352 m.

Cost of fencing for one meter = 7

Cost of fencing for 352 meters = 352 x 7 = 2464

Hence, the cost of fencing the circular park is 2464.

The diameter of a circular park is 168 m. Find the cost of fencing it at 9 per meter.

Answer: 4752

SOLUTION 1 :

Given,

Diameter of the wheel = 168m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~168~~²⁴

= 22 x 24

= 528 m.

Cost of fencing for one meter = 9

Cost of fencing for 528 meters = 528 x 9 = 4752

Hence, the cost of fencing the circular park is 4752.

The diameter of a circular park is 56 m. Find the cost of fencing it at 8 per meter.

Answer: 1408

SOLUTION 1 :

Given,

Diameter of the wheel = 56m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 56⁸

= 22 x 8

= 176 m.

Cost of fencing for one meter = 8

Cost of fencing for 176 meters = 176 x 8 = 1408

Hence, the cost of fencing the circular park is 1408.

The diameter of a circular park is 154 m. Find the cost of fencing it at 7 per meter.

Answer: 3388

SOLUTION 1 :

Given,

Diameter of the wheel = 154m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~154~~²²

= 22 x 22

= 484 m.

Cost of fencing for one meter = 7

Cost of fencing for 484 meters = 484 x 7 = 3388

Hence, the cost of fencing the circular park is 3388.

The diameter of a circular park is 126 m. Find the cost of fencing it at 8 per meter.

Answer: 3168

SOLUTION 1 :

Given,

Diameter of the wheel = 126m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~126~~¹⁸

= 22 x 18

= 396 m.

Cost of fencing for one meter = 8

Cost of fencing for 396 meters = 396 x 8 = 3168

Hence, the cost of fencing the circular park is 3168.

10)

The diameter of a circular park is 63 m. Find the cost of fencing it at 7 per meter.

Answer: 1386

SOLUTION 1 :

Given,

Diameter of the wheel = 63m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 63⁹

= 22 x 9

= 198 m.

Cost of fencing for one meter = 7

Cost of fencing for 198 meters = 198 x 7 = 1386

Hence, the cost of fencing the circular park is 1386.
