Question

If a sphere has a radius of 4.5cm what would its total csa

Answer 1

The curved surface area of a sphere is 254.57 cm².

Step-by-step explanation:

The formula to compute the curved surface area (CSA) of a sphere is,

$CSA=4\pi r^{2}$

Given:

r = 4.5 cm

Compute the value of CSA as follows:

$CSA=4\pi r^{2}\\=4\times \frac{22}{7}\times 4.5^{2}\\=254.57$

Thus, the curved surface area of a sphere is 254.57 cm².
