5. If the area of the circle is 81īt units?, what is the circumference of the circle

Step-by-step explanation:

Given that,

Area of a circle is 8π unit².

Perimeter of circle?

Now

To get the perimeter of the circle, we need to find the radius of the circle from the area given

Area of a circle is given by

A=πr²

Where A =8π

8π=πr²

Then, divide both side by π

8π/π=πr²/π

8=r²

Take square of both sides

√8=√r²

r=2√2 unit

Now we can find the perimeter of the circle

The perimeter of the circle is given as

P=2πr

P=2•π•2√2

P=17.77units

The perimeter of the circle is 17.77units

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7
