Answer:_______________

The diameter of a circular park is 35 m. Find the cost of fencing it at 6 per meter.

Answer: 660

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 = 6

Cost of fencing for 110 meters = 110 x 6 = 660

Hence, the cost of fencing the circular park is 660.

The diameter of a circular park is 56 m. Find the cost of fencing it at 5 per meter.

Answer: 880

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 = 5

Cost of fencing for 176 meters = 176 x 5 = 880

Hence, the cost of fencing the circular park is 880.

The diameter of a circular park is 126 m. Find the cost of fencing it at 5 per meter.

Answer: 1980

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 = 5

Cost of fencing for 396 meters = 396 x 5 = 1980

Hence, the cost of fencing the circular park is 1980.

The diameter of a circular park is 196 m. Find the cost of fencing it at 5 per meter.

Answer: 3080

SOLUTION 1 :

Given,

Diameter of the wheel = 196m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~196~~²⁸

= 22 x 28

= 616 m.

Cost of fencing for one meter = 5

Cost of fencing for 616 meters = 616 x 5 = 3080

Hence, the cost of fencing the circular park is 3080.

The diameter of a circular park is 161 m. Find the cost of fencing it at 8 per meter.

Answer: 4048

SOLUTION 1 :

Given,

Diameter of the wheel = 161m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~161~~²³

= 22 x 23

= 506 m.

Cost of fencing for one meter = 8

Cost of fencing for 506 meters = 506 x 8 = 4048

Hence, the cost of fencing the circular park is 4048.

The diameter of a circular park is 154 m. Find the cost of fencing it at 9 per meter.

Answer: 4356

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 = 9

Cost of fencing for 484 meters = 484 x 9 = 4356

Hence, the cost of fencing the circular park is 4356.

The diameter of a circular park is 119 m. Find the cost of fencing it at 7 per meter.

Answer: 2618

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 = 7

Cost of fencing for 374 meters = 374 x 7 = 2618

Hence, the cost of fencing the circular park is 2618.

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.

The diameter of a circular park is 70 m. Find the cost of fencing it at 7 per meter.

Answer: 1540

SOLUTION 1 :

Given,

Diameter of the wheel = 70m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x 70¹⁰

= 22 x 10

= 220 m.

Cost of fencing for one meter = 7

Cost of fencing for 220 meters = 220 x 7 = 1540

Hence, the cost of fencing the circular park is 1540.

10)

The diameter of a circular park is 91 m. Find the cost of fencing it at 9 per meter.

Answer: 2574

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 = 9

Cost of fencing for 286 meters = 286 x 9 = 2574

Hence, the cost of fencing the circular park is 2574.
