surface area and volume of a cylinder
A cylinder’s volume is π r² h, and its
surface area is 2π r h + 2π r²
surface area and volume of a sphere
Surface Area of a Sphere A = 4 π r2
Volume of a Sphere V = (4 ⁄ 3) π r3
area and volume of a cone
The area of a cone is A = πr√(r² + h²) + πr²
while the volume of a cone is V = πr² ⋅ h⁄3.
hypotenuse is the what of the right angle triangle
