Please help! !!!!!!50 POINTS!!!!!!! Question bellow!!
Sergeeva-Olga [200]
Area = πr²
Area = 3.14* 6²
A = 3.14 * 36
A = 113.04

Now find the area of the other one. 

<span>Area = πr²
A = 3.14 * 0.75</span>²
A = 1.76625

Now subtract them. 

113.04 - 1.76625 = 111.27375
Now, we have our answer: A = <span>111.27375

However, I don't see why they told you to have an exact answer for the area. You can't have an exact answer when you use 3.14 for pi.</span>
