Question

What is the approximate radius of a sphere whose volume is 1,349 cm^3 ?

Answer 1

Volume of a sphere = 3/4 x pi x r^3

1,349 = 3/4 x pi x r^3
1,349 / 0.75 x pi = 572.433.... = r^3
cube root of 572.433... = 8.30 (to 2dp)

My shape knowledge is substandard, so sorry if I'm wrong, but that's the right method I believe :)

Answer 2

Answer:

look below please

Step-by-step explanation:

Volume of a sphere = 3/4 x pi x r^3

1,349 = 3/4 x pi x r^3

1,349 / 0.75 x pi = 572.433.... = r^3

cube root of 572.433... = 8.30 (to 2dp)
