Answer 4

Oh ok! I see. Let me help you! First let's find the area of the square, cuz that one is easy. What is the area of the square?

Answer 5

400

Answer 6

What we have in this problem is a Square, formula \[s^2\] and 3/4 of a circle with a radius 20, \[\pi*r*2*(3/4)\]

Answer 7

The second formula should read \[\pi*r^2*(3/4)\]

Answer 8

Very cool. Now for the circle, we have the area as
\[A _{circle}=\pi*r ^{2}\]

Answer 9

whats the radius

Answer 10

The one side of the square also serves as the radius of the circle. Look at it again.

Answer 11

so 90?

Answer 12

oh wait
