Question

Surface area of a sphere with a diameter of 17.5 inches

Answer 1

Answer:

surface area of the sphere $=961.59inches^2$

Step-by-step explanation:

Surface area of a sphere= $4*\pi *r^2$

$Diameter= 17.5 inches$

$Radius= 17.5/2= 8.75 inches$

Surface area of the sphere$=4*\pi *8.75.8.75$                        

                               $=4*3.14*8.75*8.75$                              :$\pi =3.14$

                                $=4*3.14*76.57\\\\=12.56*76.56$

                                 $=961.59inches^2$

So, the surface area of the sphere $=961.59inches^2$
