Question

can anyone help me with this question:  find the area for each circle with a radius of 2.2 cm  I will award a medal

anonymous · Answer

This is very similar to the previous problem

Area = pi(r)^2

r = 2.2

pi(2.2)^2

Can you solve from here?

anonymous · Answer

not really sure

anonymous · Answer

Well first you should square 2.2

2.2^2 = 4.84

This leaves you with 4.84pi

Do you remember what I said the value of pi was?

anonymous · Answer

pi is 3.12

anonymous · Answer

so my answer would be 15.2

anonymous · Answer

3.14 actually :) You are going to need to remember that for the rest of your life. It will come up so often

Multiply 4.84 with 3.14

(4.84)(3.14) = ?

Correct Punkchick. The other guy was correct in the process except that he used 2.2^2 = 4.48 not 4.84
