Question

the total surface area if a right circular cylinder without lid be 2002 sq cm. If the radius if the base be 7 cm, find the quantity of water contained in the pot​

Answer 1

Answer:

5.929 litres

Step-by-step explanation:

Given,

TSA = 2002 cm², radius = 7 cm.

∴ TSA = 2πr(r + h)

⇒ 2002 = 2π * 7(7 + h)

⇒ 2002 = 2 * 22/7 * 7(7 + h)

⇒ 2002 = 2 * 22 * (7 + h)

⇒ 2002 = 44 * (7 + h)

⇒ 45.4 = 7 + h

⇒ h = 38.5 cm

Then,

Volume = πr²h

            = (22/7) * (7)² * 38.5

            = 5929 cm³

            = 5.929 litres.

Hope it helps!
