Answer:

<em>3.950121805833336 ≈ 4 m</em>

Step-by-step explanation:

The area of a circle is calculated using this formula: <u>A= πr²</u>. Since we know the area of the circle is 154 we have all the values we need to solve this problem.

154 = πr²

√154 = πr

12.40967... = πr

12.40967.../π = r

3.950121805833336 = r

<em>3.950121805833336 ≈ 4 meters </em>

Perimeter: 19 cm ( I added 5.5+7.5+6)

The length of each side of the square: 8 cm

We know that the area is 64 cm2

A=a*a (length times length) We get 8 (because we know the times tables)

Volume: 100
