Im having a really hard time.
a science museum has a spherical model of the earth with a diameter of 8.5 m. what is the volume of the model? use 3.14 for pi and round your answer to the nearest whole number. show your work.

V = 321 m^3

Step-by-step explanation:

Volume of a sphere

V = 4/3 pi r^3

The radius is equal to

r = d/2

r = 8.5/2 =4.25

V =4/3 (3.14) (4.25)^3

V =321.3920833 m^3

Rounding to the nearest whole number

V = 321 m^3

answer: the answer to your question is parallel

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !
