Answer :

Answer:

a) Surface Area of a Sphere:

[ A = 4pi r^2 ]

b) Volume of a Sphere:

[V = frac{4}{3}pi r^3 ]

Given that the radius (r) of the sphere is 8 cm, let's calculate its surface area and volume:

a) Surface Area:

[ A = 4pi(8)^2 ]

[ A = 4\pi \times 64 ]

[ A = 256\pi ]

b) Volume:

[ V = frac{4}{3}\pi(8)^3 ]

\[ V =frac{4}{3}pi times 512 ]

[ V = frac{2048}{3}pi]

So, for a sphere with a radius of 8 cm:

a) Surface area ≈ ( 256\pi ) square centimeters

b) Volume ≈ ( frac{2048}{3}pi ) cubic centimeters

if any doubt, then ask and if not, mark as brilliant and give heart.

Thankyou!
