What is the curved surface area of a sphere and hemisphere?

Curved Surface Area: The area of the outer surface of the hemisphere is called the curved surface area. From the surface area of a sphere, we can easily calculate the surface area of the hemisphere. The curved surface area of a hemisphere = 2πr2 square units.

WHAT IS curve surface area?

Curved Surface Area- The curved surface area is defined as the area of only curved surface, leaving the circular top and base. Total Surface Area- It is the area of the curved surface as well as the bases. Formula for calculating the Curved Surface Area (C.S.A.)-

What is the area of hollow sphere?

The Curved surface area of hollow sphere is the area of the paper that can completely cover the surface of the hollow sphere. It is equal to the CSA of inner sphere subtracted from the CSA of outer sphere.

What shape is the base of a sphere?

A right cone is a cone with its vertex directly above the center of its base. has a circular base that is joined to a single point (called the vertex). A sphere is a three-dimensional solid consisting of all points that have the same distance from a given center….Surface Area of a Cone.

s 2	=	​ + × π
s	=	​ + ×

How do you find the curved surface area of a circle?

2πr is the circumference of the circle and h is the height. Area of the curved surface will be = 2πr × h = 2πrh.

What is the curved surface area of hollow cylinder?

The inner curved surface area = 2πr × Height, the outer curved surface area = 2πR × Height. Solved Examples on Hollow Cylinder: A hollow copper pipe of inner radius 3 cm and outer radius 4 cm is melted and changed into a solid right circular cylinder of the same length as that of the pipe.

How does sphere shape look like?

A sphere is a round, ball-shaped solid. It has one continuous surface with no edges or vertices.
