The radius of a sphere is 1.8 cm. Find the exact volume (in $$cm^3$$​) of this sphere.

Correct option is A

Given:

Radius of sphere =1.8cm

Formula Used:

Volume of sphere =$$\frac{4}{3}\times\pi \times (r^3)$$​​

Solution:

Volume of sphere =$$\frac{4}{3}\times\pi \times ((1.8)^{3})$$​​

​$$= \frac{4}{3}\times \pi \times (5.832)$$​​

​$$= 7.776\pi cm^{3}$$​​
