Question

the surface area of a sphere is 2464cm2 if it's radius be doubled what will be the surface area of the new sphere​

Answer 1

Answer:

New Surface Area = 9856 centimeters square

Step-by-step explanation:

Surface Area of the sphere is given to be 2464 centimeters square'

Now, the formula for the surface area of the sphere is given by :

Surface Area = 4π × Radius²

⇒ Surface Area = 4π × r²

⇒ 2464 = 4π × r²

Now, Radius is doubled, ⇒ R = 2r

⇒ New Surface Area = 4π × R²

⇒ New Surface Area = 4π × (2r)²

                                  = 4π × 4r²

                                  = 4 × 4π × r²

                                  = 4 × 2464

                                  = 9856 centimeters square

∴ Surface area of the new sphere​ = 9856 centimeters square
