is 7cm. The volume of water
is *
O 196 sq cm
198 sq cm
O 66 sq cm
O None of these​

Answer 1

66 sq cm 7 cm squr and 3 cm squr

Answer 2

Correct Question :-

• A glass in the shape of a right circular cylinder is full of water. Its base radius is 3cm and height is 7cm. The volume of water is

Given :-

• Radius of Glass = 3cm
• Height of Glass = 7cm

To Find :-

• Volume of the Water.

Solution :-

⇒ Volume of Glass = πr²h

⇒ Volume of Glass = 22/7 × (3)² × 7

⇒ Volume of Glass = 22/7 × 3 × 3 × 7

⇒ Volume of Glass = 22 × 9

⇒ Volume of Glass = 198cm²

________________

Therefore, Volume of Water is 198cm² ( Option B )
