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
Invert the denominator and multiply to get 11/2= 55/24= 2 7/24 let me know if this helps ok
.8 is bigger than a half. Because 1/2 =. 5
Answer:
X=3.5
Step-by-step explanation:
AD = 4+3 = 7
ED = X
that is the ADE triangle
AB= 4
CB = 2
this is the ABC triangle
because the A angle shares the same triangles
ED /CB = AD/ AB
X/2 = 7/4
by multiplying all of the equation by 2 to get rid of the 2 under the x
X= 7/2 which is 3.5
so X= 3.5
It’s the last one because it’s bigger number and sign
