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
