Answer:_______________

The diameter of a circular park is 98 m. Find the cost of fencing it at 7 per meter.

Answer: 2156

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 = 7

Cost of fencing for 308 meters = 308 x 7 = 2156

Hence, the cost of fencing the circular park is 2156.

The diameter of a circular park is 35 m. Find the cost of fencing it at 4 per meter.

Answer: 440

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 = 4

Cost of fencing for 110 meters = 110 x 4 = 440

Hence, the cost of fencing the circular park is 440.

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 63 m. Find the cost of fencing it at 5 per meter.

Answer: 990

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 = 5

Cost of fencing for 198 meters = 198 x 5 = 990

Hence, the cost of fencing the circular park is 990.

The diameter of a circular park is 126 m. Find the cost of fencing it at 6 per meter.

Answer: 2376

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 = 6

Cost of fencing for 396 meters = 396 x 6 = 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 5 per meter.

Answer: 2310

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 = 5

Cost of fencing for 462 meters = 462 x 5 = 2310

Hence, the cost of fencing the circular park is 2310.

The diameter of a circular park is 105 m. Find the cost of fencing it at 5 per meter.

Answer: 1650

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 = 5

Cost of fencing for 330 meters = 330 x 5 = 1650

Hence, the cost of fencing the circular park is 1650.

The diameter of a circular park is 154 m. Find the cost of fencing it at 5 per meter.

Answer: 2420

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 = 5

Cost of fencing for 484 meters = 484 x 5 = 2420

Hence, the cost of fencing the circular park is 2420.

The diameter of a circular park is 105 m. Find the cost of fencing it at 8 per meter.

Answer: 2640

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 = 8

Cost of fencing for 330 meters = 330 x 8 = 2640

Hence, the cost of fencing the circular park is 2640.

10)

The diameter of a circular park is 91 m. Find the cost of fencing it at 6 per meter.

Answer: 1716

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 = 6

Cost of fencing for 286 meters = 286 x 6 = 1716

Hence, the cost of fencing the circular park is 1716.
