Answer:
Step-by-step explanation:
Volume of the figure = Volume of cone + Volume of hemisphere
Cone:
height h = 33 m
Diameter = 30m
Radius r = 30/2 = 15 m
Volume of Cone:
Hemisphere:
Radius r = 15 m
Volume of Hemisphere =
Volume of the figure = 2475π + 2250π = 4725π m²
These are the answers, and how I grouped them up.
Answer:
The cross section of sphere is circle
Area of cross section = 25 in²
Step-by-step explanation:
From the figure we can see a cylinder with height 8 inches and volume 200 π in³.
<u>The cross section of the cylinder looks like a circle.</u>
<u>To find the area of cross section</u>
Volume of cylinder = Cross section area * Height
200 = cross section area * 8
cross section area = 200/8
= 25 in²
Area of cross section = 25 in²
Answer:
82m²
Step-by-step explanation:
split it into a rectangle and square
3x6=18
8x8=64
total area = 82
