Answer:
2769.48 sq. mm
Step-by-step explanation:
The formula for the surface area of a hemisphere is 2πr^2. Using the formula(and approximating pi as 3.14) the answer of 2769.48 is reached. Approximate that however you want.
Hope this helps!
First find the volume of the cylinder, then the volume of the cone, and after you can add the two volumes.
Cylinder:
V = π r^2 h
h = 12 inches
r = 4 inches
V = π(4^2)(12)
V = 192π
Cone:
V = 1/3 π r^2 h
h = 6 inches
r = 4 inches
V = 1/3 π (4^2)(6)
V = 32π
Now adding the two volumes, 192π + 32π = 224π cubic inches
A is correct because it’s the only answer that starts with five
