Step-by-step explanation:
let x represent the bus
6x + 21 = 195
6x = 195 - 21
6x =174
x = 29
The answer would be 942.
since the formula for volume of a cylinder is the area of the base times the height you would need to multiply pi times 10^2 and then times the height of 3.
3.14 * 10^2 = 314
314 * 3 = 942
I hope this helped :)
