If 1 gallon of paint covers 400 square feet about how many gallons of paint are needed to paint the outside of a spherical tank of diameter 20 feet?
Surface area of a sphere = 4*pi*radius2 Area = 4*pi*102 = 400*pi square feet Amount needed in gallons = (400*pi)/400 = pi (3.141592654) Just over 3 gallons will be needed.
What is the radius of a circle with an area of 400Π cm squared?
A = pi R^2 = 400 pi R^2 = 400 R = 20
Find the circumference of a circle if the area is 400 Pi meters?
First we have to find the radius: pi*radius2 = 400*pi square meters Divide both sides by pi and then square root both sides: radius = 20 meters 2*pi*radius or pi*diameter = circumference 2*pi*20 = 40*pi meters
What is the volume of a cylinder that has a radius of 20 and height of 26?
pi r2h =pi(20)2(26) =pi(400)(26) =(10400)pi =32656
How do you find the perimeter and area of a circle?
perimeter (circumference): diameter times pi (3.14) area: radius times radius times pi (3.14) Area = pi*radius squared Circumference = 2*pi*radius or pi*diameter
What is the area of a circle if the diameter is 400 feet?
Area = pi times radius2 where radius = 200 feet therefore area = pi times 2002 Area = 125 663.7 feet2
Find the area of a circle with the diameter of 40m?
The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
What is pi times pi divided by pi plus pi minus pi times pi?
the same as pi squared, which is 9.86960440109
What is the diameter of a circle is the area is 400pie?
area = pi x diameter squared/4 = 400 pi diameter squared = 4 x 400 x pi/pi = 1600 diameter = sqrt 1600 = 40

How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
What are the two formulas for circumference?
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
Why is circumference equal to 2 times Pi times r?
circumference=pi circumference=pi circumference=pi
What is pi times pi equal?
pi^2
