Pie x r^2
3.14x 4^2 = 50.24 cm^2 (area of circle)
basexheight divided by 2
8x4 divided by 2 = 16 cm^2 (area of triangle)
50.24-16= 32.24 cm^2
why i chose 8=
the radius is 4 so base (diameter) = 8

Answer:
Return on investment (ROI) = 7%
Step-by-step explanation:
Given:
Amount invested = $10,000
Total amount get (refund) = $10,700
Find:
Return on investment (ROI) = ?
Computation:
Amount Return = Total amount get (refund) - Amount invested
Amount Return = $10,700 - $10,000
Amount Return = $700
Return on investment (ROI) = 7%
3/4 equals .75, and 60% equals .60. Therefore, we can set up an equation. .75=.60x, where x is the number we are looking for.
Divide each side by .60 to get the variable by itself. .75/.60= 1.25.
Hope this helped!!! :)
