Question

base area of circular cylinder is 154cmsqare then find its radius

Answer 1

Answer:

r≈7

AB Base area

154

Unit Conversion:

Using the formula

AB=πr2

Solving forr

r=AB

π=154

π≈7.00141

Answer 2

✬ Radius = 7 cm ✬

Step-by-step explanation:

Given:

• Base area of circular Cylinder is 154 cm²

To Find:

• What is the measure of its radius?

Solution: Let the measure of radius be r .We know that

★ 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 = 7 x 7

$\small\implies{\sf }$ r² = 49

$\small\implies{\sf }$ r = √49

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

Hence, the measure of radius of is 7 cm.
