Question

A spherical pear of radius 4 cm is to be divided into eight equal parts by cutting it in halves along the same axis. Find the surface area of each of the final piece

Answer 1

Answer:

Radius of spherical pear = 4 cm

Total surface area = $4\pi r^{2}$

$=4*3.14*4^{2}\\=3.14*64\\=200.96$

Its then divided into 8 equal parts:-

$\frac{200.96}{8}\\25.12$

therefore each and every part have 25.12
