Answer:Surface area of a rectangular prism is 2LW+2LH+2WH
Surface area is 82 sq. in
Step-by-step explanation:
To find area
R*R*3.14
D=8
R=4
4*4*3.14= 50.24in
I multiplied the dimensions and divided it by 75, got 8.75 but you need to round in this situation, so 9
hope this helps :)
Answer: A
Step-by-step explanation:
The area of the square is 10^2 = 100.
The area of the circle is (pi)(5^2) = 25pi.
So, the area of the region in the square but not in the circle is 100 - 25pi.
Thus, the desired probability is (100-25pi)/100, which is about 21.5%
Answer:
9
Step-by-step explanation:
n2-27=6n
Than n (exponet) 2 - 27 - 6n = 0
Now factor (n-9)(n+3)=0
