Question

A circle has an area of 50 square meters. Which answer is closest to the measure of its diameter?in meters please

Answer 1

Explanation:

we know that

Area of a circle is equal to

A=pi* r^{2}

where

r is the radius

in this problem we have that

A=50 m^{2}

A=pi* r^{2} \\ r= \sqrt{A/pi} \\ r= \sqrt{50/pi}

r=4 m

we know that

the diameter is two times the radius

so

D=2r \\ D=2*4 \\ D=8 m
