Okkaay so this would be 3.14 x (5x5) x 9 = <span>706.5

Surface area of the prism= surface area of the base + surface area of the two triangles + surface area of the two rectangles.
Surface area of the base=(3 yd * 7 yd)=21 yd².
Surface area of the two triangles=2*(3 yd * 4 yd)/2=12 yd².
Surface area of the two rectangles=(7 yd * 5 yd) + (7 yd * 4yd)=35 yd² + 28 yd²=
=63 yd²
Surface of the prism=21 yd² + 12 yd² + 63 yd²=96 yd²
Remember:
surface area of a triangle=(base * height)/2
surface area of a rectangle=base * height.
Answer: C.96 yd²
Hello
Answer:
The correct answer is B
Step-by-step explanation:
You just use the Distribuatd property to solve
You multiply 10 to all the varibles inside the parthense
Becasued y is equal to 7 you would do 10x7=70
then 10x8=80
and 70+80=150
and the answer says the primeter is 150 when y=7
Hope this helps
