8
Step-by-step explanation:
8x3=24
minus 15 is 9

therefore, the answer is 9.
Answer: 1 5/12
Because 2/3 + 3/4 = 17/12, if you simplify that it would be 1 5/12
Answer:
SA = 680 units^2
V =1200 unit^3
Step-by-step explanation:
If the radius is 5 then the diameter is 2r = 2*5 = 10
The height would remain the same
Surface area of a prism is given by
SA = 2 (lw+lh+hw)
l =d = 10 w = d = 10 h = 12
SA = 2 ( 10*10 + 10 * 12+ 12* 10)
SA = 2( 100+120+120)
SA = 2(340)
SA = 680 units^2
V = l*w*h = 10*10*12 =1200 unit^3
I think it's D. 163, or B. 133
