The number is 454.
This is because since the ones digit is 4 and the hundreds digit is the same as the ones digit, the hundreds digit is 400.
400 + 50 + 4 = 454
It is 2.74 and if you have to round it ,it is 3.
Well if you are given the radius, you can solve for it. As the volume of a cylinder is area of the base which is a circle times it height.
B • h = Pi r ^2 • h = 392 cm^3.
H = 392/Pi r^2.
This is the height or length.
You multiply the exponents together to get a single exponent, in this case, 15
