What is the circumference of a circle that has a square area of 32?
I assume you mean the circle's area is 32 square units: area = π x radius2 ⇒ radius = √(area ÷ π) circumference = 2 x π x radius = 2 x π x √(area ÷ π) = 2 x √(area x π) ⇒ circumference =2 x √(32 x π) ~= 20 units.
How does the dimensions of a cylinder help you to find its surface area?
Total Surface Area of Cylinder = 2 x pi x radius x (radius + height)Surface area of base circle = pi x radius x radiusSurface area of curved part = 2 x pi x radius x heightHence, total surface area = (2 x area of base circle) + (area of curved part)= (2 x pi x radius x radius) + (2 x pi x radius x height)= 2 x pi x radius x (radius + height)
What is the steps of finding the surface area of a cylinder?
Base Area = pi x radius x radius Curved Surface Area = 2 x pi x radius x height Total Surface Area = 2 x pi x radius x (radius + height)
Area of a triangle 2.7 x 5.2 x 6.5?
what is the area of a triangle 2.7 x 5.2 x 6.5
What is the perimeter of a circle that has an area of 28.3 square feet?
circumference ~= 18.9 ft area = π x radius2 ⇒ radius = √(area/π) circumference = 2 x π x radius ⇒ circumference = 2 x π x √(area/π) ⇒ circumference = √(4 x π x area) ⇒ circumference = √(4 x π x 28.3 ft2) ~= 18.858 ft
