Step-by-step explanation:
Area of Rectangle at the top =
Length x Width

Area of Quarter- Circle = 1/4 x Area of Circle

Area of Rectangle at the right = Length x Width

Total Area = Area of 2 Rectangles + Area of Quarter Circle

I will leave the answer in terms of pi as I'm not sure if you need to round off your answer.
Do 24/30, which is 0.8. Convert this to a percentage
==============> 80%

Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a prism: 2wl +2lh+2hw
Where w is the width of the prism; l the length; and h the height.
Replacing with the values given:
S (smaller prism) = 2 (4x6) + 2(6x2)+ 2(2x4)=48+24+16= 88 in2
S (larger prism) = 2 (8x10) +2 (10 x5)+2(5x8)= 160+100+80=340in2
Adding both surface areas:
88+340 =428 in2
