4 goes in the blank.
In math, if any number like that is 5 or higher, it rounds to the nearest tenth.
so for example, 4 would round down to 0, and 5 would round up to 10.
So with the 4, it Makes 149.6k, which rounds down to 100,000.
Answer:
V =96 pi
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h
Where r is the radius and h is the height
V = 1/3 pi (6)^2 *8
V = 1/3 pi (36)8
V =96 pi
Smaller circle:
diameter = 9 ft
radius = diameter/2 = (9 ft)/2 = 4.5 ft
A = pi(r^2) = 3.14159 * (4.5 ft)^2 = 63.62 ft^2
Larger circle:
diameter = 20 ft
radius = diameter/2 = (20 ft)/2 = 10 ft
A = pi(r^2) = 3.14159 * (10 ft)^2 = 314.159 ft^2
Difference = larger are - smaller area
Difference = 314.16 ft^2 - 63.62 ft^2 = 250.54 ft^2
Answer: About 251 ft^2
They are similar , scale factor is 3
