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

1) d = 2000/3 m

2) r =    500/3 m

Step-by-step 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
