Question

Is this correct?

Answer 1

I have some of the answers, but I do not know how to find them...

Answer 2

To find the sector, first we have to find the area of the circle right?

Answer 3

Since the radius is 25 the equation will look like this
25 * 25 * 3.14 = 1962.5

Answer 4

Why did you divide 18/360?

Answer 5

This is so confusing. Anyway there's 20 sectors that are equal, so don't we just have to divide 20 from the area? And I got the answer 98.13

Answer 6

a little different from yours.

Answer 7

25 * 25 * 3.14 = 1962.5
1962.5/20 = 98.125

Answer 8

It was just a miss calculation. He's equation's answer turned out like mine too.
0.05 * 25 * 25 * 3.14 = 98.125

Answer 9

Np :) Sorry for the late reply, I was having lunch.
