Answer:
305.78 in2
Step-by-step explanation:
The rocket has two parts: one is a cylinder and the other is a cone.
To find the total volume of the rocket, we need to find firstly the volume of each part.
The cylinder has a radius of 2 inches and a height of 2*12 + 5 - 7 = 22 inches, so its volume is:
V1 = pi * r^2 * h = pi * 2^2 * 22 = 276.46 in2
The cone has a radius of 2 inches and a height of 7 inches, so its volume is:
V2 = (1/3) * pi * r^2 * h = (1/3) * pi * 2^2 * 7 = 29.32 in2
Then, we have that the volume of the rocket is:
V = V1 + V2 = 276.46 + 29.32 = 305.78 in2
Answer:
8
Step-by-step explanation:
18+8=26
26 / 3 = 8

It's 53. You have to put the numbers in order, then tick off a number from each end until you get to the middle. That is your number.
Y = 3x/4 - 1
Taking (-1-2)/(0-4) gives the slope of the line to be 3/4. Substituting x = 0 gives the y-intercept as -1.
