Answer:_______________

The diameter of a circular park is 63 m. Find the cost of fencing it at 6 per meter.

Answer: 1188

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 = 6

Cost of fencing for 198 meters = 198 x 6 = 1188

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

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 168 m. Find the cost of fencing it at 4 per meter.

Answer: 2112

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 = 4

Cost of fencing for 528 meters = 528 x 4 = 2112

Hence, the cost of fencing the circular park is 2112.

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 147 m. Find the cost of fencing it at 7 per meter.

Answer: 3234

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 = 7

Cost of fencing for 462 meters = 462 x 7 = 3234

Hence, the cost of fencing the circular park is 3234.

The diameter of a circular park is 105 m. Find the cost of fencing it at 9 per meter.

Answer: 2970

SOLUTION 1 :

Given,

Diameter of the wheel = 105m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~105~~¹⁵

= 22 x 15

= 330 m.

Cost of fencing for one meter = 9

Cost of fencing for 330 meters = 330 x 9 = 2970

Hence, the cost of fencing the circular park is 2970.

The diameter of a circular park is 154 m. Find the cost of fencing it at 6 per meter.

Answer: 2904

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 = 6

Cost of fencing for 484 meters = 484 x 6 = 2904

Hence, the cost of fencing the circular park is 2904.

The diameter of a circular park is 133 m. Find the cost of fencing it at 5 per meter.

Answer: 2090

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 = 5

Cost of fencing for 418 meters = 418 x 5 = 2090

Hence, the cost of fencing the circular park is 2090.

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.

10)

The diameter of a circular park is 91 m. Find the cost of fencing it at 4 per meter.

Answer: 1144

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 = 4

Cost of fencing for 286 meters = 286 x 4 = 1144

Hence, the cost of fencing the circular park is 1144.
