The area of a circle is 78.5 cm² . Find the lenght of the radius of a circle . Use π = 3.14

Tpy6a [65]

Answer:

5cm = r

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

78.5 = 3.14 r^2

Divide each side by 3.14

78.5/ 3.14 = r^2

25 = r^2

Take the square root of each side

sqrt(25) = sqrt(r^2)

5 = r
