Answer:
B. 7.9 in^2
Step-by-step explanation:
Part I.
Finding the fraction of the circle that is the sector
To start, let’s find the fraction of the circle that the sector covers. Since the measure of the central angle is 36, we get 36/360 or 1/10 of the circle.
Part II.
Finding the area of the Circle
The area of a circle is pi*r^2. Since r=5, then the area is 25pi.
Part III.
Finding the area of the sector.
Since the sector is 1/10 of the circle, its area is 1/10 of the circle’s area. So the area of the sector is 25/10*pi or (5/2)pi. This is approximately 7.9 in^2.
If there are 30 Apple computers and 7 of the computers have a specialized movie editing software, then that would be 23.3333333% of the Apple computers can be used for editing movies.
7/30x100= 700/30
700/30= 23.33%
Answer:3150
Step-by-step explanation:
70% of 10,000 is 7000. 45% of 7000 is 3150
Triangle=1/2 times base times height
base=32
height=24
the lateral surface area is not including bottom so just the 4 side triangles
4 times 1/2 times base times height
4 times 1/2 times 32 times 24
2 times 32 times 24
1536
lateral surface area is 1536 square centimeters
