The area of a circle is 200.96 square kilometers. what is the circle's circumference? using 3.14 as pi

we know that

the area of a circle is equal to

the circumference of a circle is equal to

where

r is the radius of the circle

in this problem we have

Step

Find the radius of the circle

so

Step

Find the circumference of the circle

therefore

the answer is

the circumference is equal to

sorry not sure

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
