Aright cylindrical solid is cut in half to form the figure shown. if the length is 20 cm and the diameter is 8 cm, what is the surface area? (80π + 160) cm2 (96π + 160) cm2 320π cm2 (320π + 160) cm2

add a pic of the graph, then ill edit this "answer" and solve it for you : 3

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
