Answer:
0.064
Step-by-step explanation:
25000(1-0.8)^8
= 25000(0.2)^8
= 0.064
20*1.95 =39 girls
26girls/39girls =0.667
0.667*100 = 66.67%
Answer:
B. 2010.62 ft³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h . . . . . where r is the radius and h is the height
Filling in the numbers and doing the arithmetic, we get ...
V = π(8 ft)²(10 ft) = 640π ft³ ≈ 2010.6193 ft³ ≈ 2010.62 ft³
The volume of the cylinder is about 2010.62 ft³.
