Question

Height of a cylinder is same as the diameter of its base. If its base radius is 7 cm then volume of the cylinder will be :
(A) 2156 cm2
(B) 1078 cm2
(C) 686 cm2
(D) 343 cm2

Answer 1

Answer:

2156 cm³

Step-by-step explanation:

Find the diameter:

Diameter = Radius x 2

Diameter = 7 x 2 = 14 cm

Find the height:

Height = Diameter = 14 cm

Find the volume:

Volume = πr²h

Volume = π(7)²(14) = 2156 cm³

Answer: (A) : 2156 cm³

Answer 2

HELLO DEAR,

Diameter = Radius x 2

Diameter = 7 x 2 = 14 cm

height of cylinder = Diameter = 14 cm

volume of cylinder = πr²h

Volume = π(7)²(14) = 2156 cm³

Hence, option (A) is correct

I HOPE IT'S HELP YOU DEAR,

THANKS
