Question

Find the volume and surface area of a sphere with radius 1 yards. Round your answer to two decimal places.

Answer 1

Answer:

Volume of the sphere up to two decimal places= $4.19$ cubic yards

Surface area of the sphere up to two decimal places  $=12.56$ square yards

Step-by-step explanation:

Given:

The radius of the sphere= 1 yard

Volume of a Sphere:

                        $\frac{4}{3}* \pi *r^3$                                                         :$\pi =\frac{22}{7} =3.14$

               $=\frac{4}{3}*3.14*1*1*1$

               $=4.187$ cubic yards

Volume of the sphere up to two decimal places= $4.19$ cubic yards

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

                                           $=4*3.14*1*1$

Surface area of the sphere up to two decimal places  $=12.56$ square yards
