Question

the volume of a solid cylinder is 352 CC and the height is 7 cm . what is the radius of its base.​

Answer 1

Answer:

4 cm

Step-by-step explanation:

Volume of a solid cylinder = πr²h = 352 cm³

Where, r = ?, h = 7 cm

Or, 22/7×r²×7 = 352

Or, r² = 352/22

Or, r² = 16

Or, r² = 4²

Or, r = 4 cm

Therefore, the radius of base of cylinder = 4 cm

Answer 2

Answer:

The radius of the base of the cylinder = 4 cm

Step-by-step explanation:

Volume of a solid cylinder = πr²h = 352 cm³

When, height = 7 cm

⇒ $\frac{22}{7}$ × r² × 7 = 352

⇒ r² = $\frac{352}{22}$

⇒ r² = 16

⇒ r² = 4²

⇒ r = 4 cm
