Step-by-step explanation:
General formula for the area of a circle = πr^2.
Since the diameter is 8, the radius is 4 (half of diameter)
So the area is π(4)^2 = 16π.
If I am reading the equation correctly, I do not believe it has a solution.
The answer would be 8 or A
Step by Step Explanation:
First you have to find the volume of the Sphere.
Set the problem up like this: V = Volume
V= 4/3 • pi (3.14) • 6(3)
= 904.32
Now you have to volume and as stated the volume and radius is the same for both the cylinder and sphere. So now you plug in the answers for the letters.
Formula for (V) Volume of Cylinder is:
V= Pi (3.14) • R (radius) (2) • H (height)
So plug in for what you know
904.32 = 3.14 • 6(2) • H
904.32 = 3.14 • 36 • H
113.04/904.32 = 113.04 • H/113.04
8 = H
The answer is A
Answer:
< F , < E, < D
Step-by-step explanation:
ΔDEF
Arrange the sides from smallest to largest
DE = 4, FD = 13, and EF = 15.
Largest side opposes the largest angle, medium side opposes the medium angle, smallest side opposes the smallest angle.
the angles of ΔDEF in order from smallest to largest
< F , < E, < D
The formula for finding c...” No, you would divide it. The formula for finding circumference is 2 x pi x r, where r is the radius. 2 x r = d, where d is diameter.
