Find the surface area of a sphere to the nearest square unit 2inches

The surface area of sphere having 2 inches radius is 50.24 inches²

Step-by-step explanation:

  Given : radius of sphere = 2 inches

We have to find the surface area of the sphere

Surface area of sphere is given by :

Given radius of sphere is 2 inches

Thus, Surface area of sphere having radius 2 inches is

Solving, we get,

Using , we get

Thus, the surface area of sphere having 2 inches radius is 50.24 inches²

where are the options?

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
