Answer 5

Okay, so we have 3/4 a circle and a rectangle.

Answer 6

ok

Answer 7

a = 10

So one of the sides of the rectangle is 10.

Plug in 10 to find the other one:

3a

3(10)

3 * 10 = ?

Answer 8

30

Answer 9

Yes, so the length is 30, and the width is 10.

\(A_{Rectangle} = lw\)

\(A_{Rectangle} = (30)(10)\)

Answer 10

Multiply 30 and 10.

Answer 11

300

Answer 12

Yes, that's the area of the rectangle, now let's do the 3/4 circle.

Answer 13

For the circle, the radius is 'a' or '10'.

We can just act like it's a whole circle and find the area of it, then we can multiply by 3/4.

\(A_{Circle} = \pi r^2\)

Plug in what we know:

\(A_{Circle} = (3.14)(10)^2\)

Simplify that
