0.3, 30% is the correct answer
Answer:
h = 18.88 inches
Step-by-step explanation:
Given that,
The circumference of a cylinder is 20 inches
The volume of the cylinder, V = 600 cubic inches
We need to find the height of the cylinder. We know that the volume of a cylinder is given by :
r is radius
We know that,
circumference = 2πr
So,
So, the height of the cylinder is 18.88 inches.
Answer:
A) Area of sector = 2.5 in².
Step-by-step explanation:
Given : If the area of the circle below is 10 in².
To find : What is the area of the shaded sector .
Solution : We have given that
Area of the circle = 10 in².
Formula of area of circle = .
= 10
=
Area of sector =
Plugging the values
Area of sector = * 10.
Area of sector = 2.5 in².
Therefore, A) Area of sector = 2.5 in².
