Answer:
Option d is correct answer.
Step-by-step explanation:
Given in the picture is a circle with a sector quadrant circle.
WE have the formula for the sector of a circle
If angle of the sector is x
then we have
area of the sector =
Here x=central angle = 90 and r = radius = 8
Substitute to get
The correct answer is A

That's it right there. That expression can't be simplified.
Radius = diameter/2 = 8/2 = 4m
Area of a circle = pi x r^2 = pi x 4^2 = 16pi m^2 ( exact area) or 50.27 m^2
Circumference = pi x diameter = 8pi m ( exact) or 25.12 m
7/10 + (-17/20)
Make the denominators equal:
14/20 + (-17/20)
Add:
-3/20
Answer:
85%
Step-by-step explanation:
If 30 of them have their own lawn service then that means 170 of them do not have their own lawn service.
Seeing as there are 200 houses in total, the fraction of people who don't have lawn service is 170/200. This is equal to 0.85 or 85%.
10.4% as a fraction is 104/1000
