1 answer:

5 0

Given that the number is C.
The number divided by 7 is C/7
Difference means we will subtract 9 from C/7.
Therefore, the equation will be:
C/7 - 9 = 2 (multiply all terms by 7 to get rid of the fraction)
C - 63 = 14
C = 14 + 63 = 77

Answer:

D. 151 cu. in.

Step-by-step explanation:

Given: Cone; Radius = 4 in, Height = 9 in.

To find: The volume of the specified cone

Formula: $V=\frac{1}{3} h\pi r^2$

Solution: A cone is a solid that has a circular base and a single vertex. To calculate its volume multiply the base area (area of a circle: π × r²) by height and by $\frac{1}{3}$ : volume = ( $\frac{1}{3}$ ) × π × r² × h.
