The diameter of a circular park is 35 m. Find the cost of fencing it at 5 per meter.

Answer:_______________

The diameter of a circular park is 98 m. Find the cost of fencing it at 6 per meter.

Answer: 1848

SOLUTION 1 :

Given,

Diameter of the wheel = 98m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 98¹⁴

= 22 x 14

= 308 m.

Cost of fencing for one meter = 6

Cost of fencing for 308 meters = 308 x 6 = 1848

Hence, the cost of fencing the circular park is 1848.

The diameter of a circular park is 84 m. Find the cost of fencing it at 9 per meter.

Answer: 2376

SOLUTION 1 :

Given,

Diameter of the wheel = 84m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 84¹²

= 22 x 12

= 264 m.

Cost of fencing for one meter = 9

Cost of fencing for 264 meters = 264 x 9 = 2376

Hence, the cost of fencing the circular park is 2376.

The diameter of a circular park is 63 m. Find the cost of fencing it at 4 per meter.

Answer: 792

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 = 4

Cost of fencing for 198 meters = 198 x 4 = 792

Hence, the cost of fencing the circular park is 792.

The diameter of a circular park is 42 m. Find the cost of fencing it at 9 per meter.

Answer: 1188

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 = 9

Cost of fencing for 132 meters = 132 x 9 = 1188

Hence, the cost of fencing the circular park is 1188.

The diameter of a circular park is 84 m. Find the cost of fencing it at 5 per meter.

Answer: 1320

SOLUTION 1 :

Given,

Diameter of the wheel = 84m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 84¹²

= 22 x 12

= 264 m.

Cost of fencing for one meter = 5

Cost of fencing for 264 meters = 264 x 5 = 1320

Hence, the cost of fencing the circular park is 1320.

The diameter of a circular park is 119 m. Find the cost of fencing it at 8 per meter.

Answer: 2992

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 = 8

Cost of fencing for 374 meters = 374 x 8 = 2992

Hence, the cost of fencing the circular park is 2992.

The diameter of a circular park is 147 m. Find the cost of fencing it at 8 per meter.

Answer: 3696

SOLUTION 1 :

Given,

Diameter of the wheel = 147m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~147~~²¹

= 22 x 21

= 462 m.

Cost of fencing for one meter = 8

Cost of fencing for 462 meters = 462 x 8 = 3696

Hence, the cost of fencing the circular park is 3696.

The diameter of a circular park is 63 m. Find the cost of fencing it at 9 per meter.

Answer: 1782

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 = 9

Cost of fencing for 198 meters = 198 x 9 = 1782

Hence, the cost of fencing the circular park is 1782.

The diameter of a circular park is 126 m. Find the cost of fencing it at 9 per meter.

Answer: 3564

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 = 9

Cost of fencing for 396 meters = 396 x 9 = 3564

Hence, the cost of fencing the circular park is 3564.

10)

The diameter of a circular park is 35 m. Find the cost of fencing it at 5 per meter.

Answer: 550

SOLUTION 1 :

Given,

Diameter of the wheel = 35m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 35⁵

= 22 x 5

= 110 m.

Cost of fencing for one meter = 5

Cost of fencing for 110 meters = 110 x 5 = 550

Hence, the cost of fencing the circular park is 550.
