Question

Please help me thanks

Answer 1

Sorry hon, just saw the comment on the last answer!

B. Approximately 7.4m

To get to the answer... the equation was 55.11= r^2, so you would just find the square root of 55.11 to eliminate r.

C. Approximately 14.8m

To get to the answer... diameter is just from one end of the circle to the opposite. This being said, it is just double the radius.

Answer 2

B) 7.4

C) 3.7

Explanation:

B) The opposite of squaring is to square root. Therefore we do the square root of 55.11 to find the radius. (√55.11)

This is 7.4 (to one decimal place)

C) The diameter is half of the radius.

We divide the value in our calculator by 2

We get 3.7 (to one decimal place)
