Question

if the diametre of a sphere is 42cm, then find its volume.

Answer 1

heya

here is ur answer

given :- diameter of sphere = 42

radius = daimeter /2

radius = 42/2

radius= 21

volume of sphere = 4/3 πr^3

$\frac{4}{3} \times \frac{22}{7} \times 21 \times 2 1 \times 21 \\ \\ 4 \times 22 \times 21 \times 21 = 38808$


➡ur answer is "38808"

Answer 2

radius of the sphere = diameter/2
radius = 42/2= 21 cm

volume of sphere =4πr^3/3

thus, volume = (4×22×21×21×21)/7×3
volume = 38808 cm^3

hope it helps u...
if yes, mark brainliest...
have a gr8 day ahead...
