Question

The volume of a cylinder is 2512 cu cm and it's height is 12.5 cm. Find the radius of its base .(take pie =3.14)

Answer 1

volume=2512 cubic cm
h=12.5 cm

volume of cylinder=pi×r^2×h
2512=3.14×r^2×12.5
r^2=2512/3.14×12.5
r=8 cm

Answer 2

CYLINDER:
v = 2512 cm³
h = 12.5 cm
r = ?

volume = πr²h
2512 = 3.14×r²×12.5
r² = 2512÷3.14×12.5
= 64

r = √64
= 8.
therefore radius of its base is 8 cm
