When a sphere is cut by a plane which passes through the center, it will create a circle that has the same diameter of the sphere.
To represent this area, you will use the formula for finding area of a circle.
A= pi x r^2
Pi x 5^2
A = 25 x pi or choice B
Answer:
88 divided by 8 is 11.
Step-by-step explanation:
You can't use the distributive property for this problem because there is no distributing to be done, but the answer is 11.
Since 30 lights are 40% of them:
30*2= 60
Since 2*40= 80
We still need the 20 percent.
Half of 40= 20.
30/2= 15
So, 15+60= 75
75 is the number of lights on the tree.
I hope this helps!
