Question

The area of circle is 154 cm sq.Find the radius of the circle.​

Answer 1

Answer:

7cm

Step by Step:

$\pi \: r {}^{2} = 154 \\ \frac{22}{7} \times r {}^{2} = 154 \\ r {}^{2} = \: 154 \times \frac{7}{22 } \\ r {}^{2} = \: 49 \\ r = \sqrt{49 } \\ r = 7$

Answer 2

Answer:

1

Step-by-step explanation:

area of circle =πrsquare

154. =22/7×r square

rsquare. =22/22

radius. =1
