Question

If the radius of the cylinder is 7cm and
volume is 462 cubic cm, then height of the
cylinder is​

Answer 1

Answer:

Height of cylinder is 12 cm.

Step-by-step explanation:

Volume of cylinder = 462 cm ^2

Diameter = 7 cm

so,

Radius = 7/2 cm

Now,

Volume = 22/7 r ^2 × h

462 = 22/7 ×7/2 ×7/2 × h

462 = 11 × 7/2 × h

462 × 2 = 77 h

(462 × 2) / 77 = h

(42 × 2 ) / 7 = h

6 × 2 = h

12 = h12=h

So,

Height of cylinder is 12 cm.
