Question

The area of right circular cone is 38.50 sq cm. Its height is three times of radius of the base. Find the volume

Answer 1

the area of right circular cone is 38.50 sq. cm.

Radius = ?

Volume = ?

pi * r² = 38.50

r= root ( 38.5 / pi)

r= 3.5 cm

if its height is 3 times of radius of the base.

h = 3 * ( 3.5 )

h= 10.5 cm

h = 10.5 cm is the height

formula of a volume is given by,

V= 1/3 * pi * 3.5² * 10.5

V= 134.7 cm³

Answer 2

Step-by-step explanation:

i.Figure.

ii.Data:

Aera of tase = A = 38.5cm

Volume = v = ?

H=height = 3r

Ā=22

7

iii.Formula.

[A = Ār]

iv.Finding rudius and height

A = Ār
