Yes, because 20 is easy to multiple by 8. it ends in 0 and anything being multiplied by 2 is easy to find. 32 times 5 isn't exactly harder to figure out because its times 5 but its just not as easy to do right off the too of your head quickly.
Answer:
Step-by-step explanation:
V = 1/3 pi r^2 h Multiply both sides by 3
3V = pi r^2 h Divide by pi * h
= r^2 Take the square root
= r
The answer would be d. 2,742
The reason for this being is because 2,742 rounded to the nearest hundred would be 2,700, but if you were to take the 2,612 rounded to the nearest hundred it would be 2,600. Also 2,742 rounded to the nearest thousand is 3,000.
