The answer is option B

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius of the circle

From the question

Area = 154cm²

To find the radius substitute this value into the above formula and solve for the radius

That's

154 = πr²

Divide both sides by π

We have

${r}^{2} = \frac{154}{\pi}$

Find the square root of both sides

Thats

$r = \sqrt{ \frac{154}{\pi} }$

r = 7.0014086

We have the final answer as

radius = 7.0 cm

Hope this helps you
