Answer:_______________

The circumference of the base of a 24m high wooden solid cone is 88m. Find the volume.

24m

2π r=88 m

Answer: 4928m³

SOLUTION 1 :

Given:

Height (h) = 24m

Circumference of cone = 88m

⇒ 2π r = 88m ⇒ 2 x $\frac{22}{7}$ x r = 88m

⇒ r = (88x7)/(2x22) = $\frac{616}{44}$

⇒ r = 14

Volume of cone = $\frac{1}{3}$ πr²h cubic units

= $\frac{1}{3}$ x $\frac{22}{7}$ x 14 x 14 x 24 = 4928m³

Volume of cone = 4928m³

The circumference of the base of a 15m high wooden solid cone is 88m. Find the volume.

15m

2π r=88 m

Answer: 3080m³

SOLUTION 1 :

Given:

Height (h) = 15m

Circumference of cone = 88m

⇒ 2π r = 88m ⇒ 2 x $\frac{22}{7}$ x r = 88m

⇒ r = (88x7)/(2x22) = $\frac{616}{44}$

⇒ r = 14

Volume of cone = $\frac{1}{3}$ πr²h cubic units

= $\frac{1}{3}$ x $\frac{22}{7}$ x 14 x 14 x 15 = 3080m³

Volume of cone = 3080m³

The circumference of the base of a 21m high wooden solid cone is 132m. Find the volume.

21m

2π r=132 m

Answer: 9702m³

SOLUTION 1 :

Given:

Height (h) = 21m

Circumference of cone = 132m

⇒ 2π r = 132m ⇒ 2 x $\frac{22}{7}$ x r = 132m

⇒ r = (132x7)/(2x22) = $\frac{924}{44}$

⇒ r = 21

Volume of cone = $\frac{1}{3}$ πr²h cubic units

= $\frac{1}{3}$ x $\frac{22}{7}$ x 21 x 21 x 21 = 9702m³

Volume of cone = 9702m³
