Question

What is the area of the following circle? Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a decimal.

the circle is r = 5 as a radius

Answer 1

25 times pi or 78.5 cm squared using 3.14 as pi.

Explanation:

Recall that the area of a circle or the formula is pi times the radius squared. If the radius is 5, to square means to take it to the power of 2. So 5 times 5 is 25. You have your radius and it is squared, so either put 25pi or change pi to 3.14 and multiply that with 25. You get 78.5 cm squared for doing. Therefore, that is the area of a circle. Hope this helps!

Answer 2

The answer is 78.5 because 5 squared is 25 and 3.14 times 25 is 78.5.
