Question

Find volume of sphere, if r= 3cm and also find TSA

Answer 1

Answer:

volume = 198/7.......

Answer 2

Step-by-step explanation:

vol.of sphere=$\frac{4}{3} \pi r^{3}$

                     =4/3*\pi*3*3*3

                     =22*36/7

                     = 113.14cm³

TSA of sphere = $\frac{4}{1} \pi r^{2}$

                         =4*22*3*3/7

                          =113.14cm²
