Question

1.) Find the hemisphere's diameter if its radius is 1000/3m

2.) Find the hemisphere's radius if it's diameter is 1000/3m​

Answer 1

1) d = 2000/3 m

2) r = 500/3 m

Explanation:

1) Diameter

The diameter of a hemisphere is twice the radius.

d = 2r

If r = 1000/3 m

d = 2 × 1000/3 = 2000/3 m

2) Radius

d = 2r

Divide each side by 2

r = d/2 = ½d

If d = 1000/3 m

r = ½ × 1000/3 = 500/3 m
