Question

Find the radius of a circle that has an area of 6.76 cm². Use it for pi.

Answer 1

Answer:

radius = 1.47 cm

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius

From the question

Area = 6.76 cm²

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

That's

$6.76 = \pi \: {r}^{2}$

Divide both sides by π

We have

${r}^{2} = \frac{6.76}{\pi} \\ r = \sqrt{ \frac{6.76}{\pi} }$

r = 1.46689291

We have the final answer as

radius = 1.47 cm

Hope this helps you
