Answer:
468.5 in
(??? gonna be honest I'm not sure its right but gave it a shot so apologies if I gave u a wrong answer)
Step-by-step explanation:
(this is how I did it, like I said, not sure its right)
<u>Dotted line: </u>
we need to find the length of the dotted line in order to be able to calculate the area of the rectangle
radius = 8 in
diameter (dotted line)
= 8 x 2
= 16 in
(radius is half the diameter so now you know the length of the dotted line is 16 in - this answer is for the rectangle)
<u>Area of the rectangle</u>
<em>A = L x W</em>
using the 16 we found to calculate the area of the rectangle
A = 23 x 16
A = 368 in
<u>Area of semi-circle:</u>
Now to calculate the area of the semi-circle
<em>A = π r² ÷ 2</em>
A = π 8² ÷ 2
= 100.48
<u>Adding the area of the rectangle and semi-circle together:</u>
= 100.48 + 368
= 468.48
1dp = <em><u>468.5</u></em>
tried to explain it as well as possible
sorry if its wrong
