Question

Find the height of a right circular cylinder of volume 28πcm³. if its radius is 2 cm.​

Answer 1

Answer:

7cm

Step-by-step explanation:

Radius  = 2cm

Volume = 28πcm³ = 28 × 22/7 = 88cm³

Formula of volume of a cylinder = πr²h

⇒ 88 = 22/7 × 2 × 2 × h

⇒ $\frac{88*7}{22*2*2}$ = h

⇒ h = 7cm

∴ Height of the cylinder is 7 cm
