Question

the area of the base of a right circular cylinder is 154 square cm and its height is 15 cm find the volume of the cylinder​

Answer 1

Answer:

2310cm^2

Step-by-step explanation:

area of base = 154cm

$\pi r^{2} =154\\r^{2} = 154*\frac{7}{22} \\r^{2} = 49$

r=7cm

vol. of cylinder=

$\pi r^{2} h\\\\=\frac{22}{7} *7*7*15\\=22*7*15\\=2310cm^{2}$

Answer 2

✬ Volume = 2310 cm³ ✬

Step-by-step explanation:

Given:

• Area of base of right circular Cylinder is 154 cm²
• Measure of height of circular cylinder is 15 cm.

To Find:

• What is measure of volume of the Cylinder?

Solution: We know area of circle :-

★ Area of circle = πr² ★

A/q

$\small\implies{\sf }$ πr² = 154

$\small\implies{\sf }$ 22/7 x (r)² = 154

$\small\implies{\sf }$ r² = 154 x 7/22

$\small\implies{\sf }$ r² = 49

$\small\implies{\sf }$ r = √49 = 7 cm

Hence, Radius of Cylinder = 7 cm and Height of Cylinder = 15 cm

★ Volume of Cylinder = (πr²h) cubic units ★

$\small\implies{\sf }$ 22/7 x (7)²(15)

$\small\implies{\sf }$ 22/7 x 49 x 15

$\small\implies{\sf }$ 16170/7

$\small\implies{\sf }$ 2310 cm³

Hence, the volume of right circular cylinder is 2310 cm³
