use the formula given:
V = pi r^2h
r = 10.55
h = 12.56
V = 3.14 x 10.55^2 x 12.56 = 4391.81 round off to 4392cm^3
answer is D 4392
Answer:
if you want answer that question go to qanda
The figure can be splitted into 2 trapeziums.
Hence, 14.5 * 16 + 20 * 10 = 432.
5) slope is y=mx+b
3) cross the y-axis
1) perpedicular to the y-axis
4) parallel
sorry it's in a random order and idk #2
