Answer:
105.12 ft^2
Step-by-step explanation:
Area of a rectangle: bh
In this case 8*10.... so area of the rectangle is 80
Area of a circle: pir^2
Half it for a semicircle.
so 1/2 pi r^2
radius is 4 cuz its half of 8.
so 1/2(3.14)(4^2)=(0.5)(3.14)(16)=25.12
Now add up 80+25.12
Total is 105.12
Hope I helped :)

<u>Answer:</u>
K = (e, d)
<u>Step-by-step explanation:</u>
We are given the coordinates of three vertices of a rectangle and we are to find the coordinates of the fourth point J.
H (0, 0)
I (0, d)
K (e, 0)
J = ?
We can find this using the following formula:
K = H + (I - H) + (K - H)
K = H + I - H + K - H
K = I + K - H
Substituting the given values in it to get:
K = 
K = 
K = (e, d)
Answer: 50
Step-by-step explanation:
A right angle is 90 degrees. A triangle must add up to 180 degrees. Add 40 and 90 to get 130. Then subtract 180 from 130 to get 50.
