Surface area of sphere?
Surface area of sphere is : A= 4*pie*r^2
What is the surface area of a spherical tank having a radius of 25cm?
The area of a sphere is Area = 4(pie)r^2 If this is a cylinrical tank with spherical ends you need the length. The area of the cylinder part is (pie)r^2 x length then add to area of sphere
The surface area for a sphere is four times the product of pie and the square of the radius?
You are correct my friend! Surface Area of a Sphere is indeed = 4(pi)r^2 and that is also equal to Circumference times Diameter!
What is the surface area of half a sphere?
its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
How do you get the circumference of a sphere?
pie times diameter is the circumference of a circle. a sphere is a 3-dimensional object and you dont take the circumference but rather you take the surface area. the circumference is to measure the total outside distance around the circle. the surface area is the measure the total outside distance around the sphere. remember a sphere is like a ball that is rounded. a circle is just a circle and can only be 2-dimensional.. like on paper
