Question

find the volume of a right,circular cylinder when the circumference of its circular base is 44 cm and its height is 10 cm

Answer 1

✬ Volume = 2310 cm³ ✬

Step-by-step explanation:

Given:

• Circular base of Cylinder is 44 cm.
• Height of Cylinder is 15 cm.

To Find:

• What is the volume of the cylinder?

Solution: We know circumference of circle is

★ Circumference = 2πr ★

A/q

$\small\implies{\sf }$ 2πr = 44

$\small\implies{\sf }$ 2 x 22/7 x r = 44

$\small\implies{\sf }$ 44/7 x r = 44

$\small\implies{\sf }$ r = 44 x 7/44

$\small\implies{\sf }$ r = 7

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 Cylinder is 2310 cm³
