Surface area of a sphere = 4πr2
width times height
How do you find the suface area of a net? Answer: Do the formula for each shape that is in the net.
Surface area of a sphere = 4 x (pi) x (radius)2
Just add the area of the six squares - that gives you 6a2, where a is the length of one side.
pi * r * (r + sqrt(r^2 + h^2))
1/3Ah That is to say, 1/3 times the area of the base times the height (not the slant height) of the cylinder
The suface are of a rectangular prism is the area of each face added together for a total.
The suface area of a sphere with a radius of 7 meters is 615.75m2
Their roots and their suface area
The formula for a rectangle is height x width (A=ab)Since you said surface area, I'm pretty sure that you might mean a rectangular prism. To get this, you would need to find the area of each "rectangle side". To do this, you use the first formula, using height (a), width (b), and depth (c). The formula for theSurface Area of a Rectangular Prism = 2ab + 2bc + 2ac
its in geelong so suck on that
