Question

If the
surface area
area of a sphete
2826 cm2
then find its volume​

Answer 1

Answer:

plz mark me as brainliest

Step-by-step explanation:

Surface area of sphere= 2826

4πr2=2826

4×3.14×r2=2826

12.56×r2=2826

r2=2826/12.56

r2=225

r=√225

r=15cm

volume of sphere=4/3πr3

=4/3×3.14× (15)3

4/3×3.14×3375

=42390/3

=14130cm3

Answer 2

Answer:

let r is the radius of the sphere

so,surface area is 4πr^sqcm

4πr^2=2826

r^2=2826/4π=2826/4×3.14=225

r=√225=15

volume of the sphere is 4/3π r^3cucm

=4/3×3.14×(15)^3cucm

=4/3×3.14×15×15×15cucm

=4×3.14×5×15×15cucm

=14130 cucm
