The diameter of a circular park is 70 m. Find the cost of fencing it at 6 per meter.

Answer:_______________

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 56 m. Find the cost of fencing it at 6 per meter.

Answer: 1056

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 = 6

Cost of fencing for 176 meters = 176 x 6 = 1056

Hence, the cost of fencing the circular park is 1056.

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 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 42 m. Find the cost of fencing it at 6 per meter.

Answer: 792

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 = 6

Cost of fencing for 132 meters = 132 x 6 = 792

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

The diameter of a circular park is 112 m. Find the cost of fencing it at 8 per meter.

Answer: 2816

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 = 8

Cost of fencing for 352 meters = 352 x 8 = 2816

Hence, the cost of fencing the circular park is 2816.

The diameter of a circular park is 70 m. Find the cost of fencing it at 9 per meter.

Answer: 1980

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 = 9

Cost of fencing for 220 meters = 220 x 9 = 1980

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

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.

The diameter of a circular park is 175 m. Find the cost of fencing it at 8 per meter.

Answer: 4400

SOLUTION 1 :

Given,

Diameter of the wheel = 175m

Lenth to be fenced = Circumference of the circular park.

circumference of wheel = πd

= $\frac{22}{7}$ x ~~175~~²⁵

= 22 x 25

= 550 m.

Cost of fencing for one meter = 8

Cost of fencing for 550 meters = 550 x 8 = 4400

Hence, the cost of fencing the circular park is 4400.

10)

The diameter of a circular park is 70 m. Find the cost of fencing it at 6 per meter.

Answer: 1320

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 = 6

Cost of fencing for 220 meters = 220 x 6 = 1320

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