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

113.04m³

Step-by-step explanation:

$Solution,\\\\Diameter(d)=6m\\\\Radius(r)=6m/2=3m\\\\Now,\\\\Volume=\frac{4}{3} \pi r^{3} \\\\Volume=\frac{4}{3} *3.14*(3m)^{3} \\\\Volume=113.04m^{3}$
