You did not include the figure, but according to the statement the viewing room of the planetarium is in the shape of a hemisphere.
A hemisphere is half a sphere.
So, the volume of a hemisphere is the half of the volume of the complete sphere.
The formula for the volume of a sphere is:
V = (4/3) π (radius)^3
Using π = 3.14 and radius = diameter / 2 = 50 feet / 2 = 25 feet.
You get:
V = (4/3) (3.14) (25 feet)^3 = 65,416.7 feet^3
Answer: 65,416.7 cu. ft.

Step-by-step explanation:
9 + 5c = 4c
9 = 4c - 5c
9 = -1c
9 / -1 = c
C = -9 or 9
Answer:
d = 40 / c
Step-by-step explanation:
There are 10 flower boxes and each holds 4 kilograms of soil. This means Ann will need 40 kilograms of soil.
So the number of bags d depends on how much soil c is in each bag. The equation is 40/c = d
