Answer: It’s the first one.
Step-by-step explanation: it’s right on edge
Answer:
g²/f⁷h
Step-by-step explanation:
Because f⁹-f²=f⁷ which leaves f⁷ on the bottom, g³-g=g² which leaves g² on the top, and h⁵-h⁴=h which leaves h on the bottom.
Answer:
87.92in³
Step-by-step explanation:
Volume of cylinder formula:

Plug in the values using 3.14 for pi:
V = 3.14(2)^2(7)
V = 87.92in³
Answer:
C.
Step-by-step explanation:
To find the area of a triangle, one must multiply the base by the height then divide by 2.
So, the area of this triangle would be 7.5
