Question

i need help on volume on a sphere stuff pleeeaasse help.

Answer 1

\[V = \frac43πr ^{3}\]

Answer 2

Same thing as before, just different formula.

Answer 3

its saying : volume of the sphere to the nearest whole number. use pi = 3.14
r=2.8 m
a. 69m^3 b. 736m^3 c. 23m^3 d. 92m^3

Answer 4

V = (4/3)π(2.8)^3
V = (4/3)(π)(2.8)(2.8)(2.8)

Answer 5

Can you do it from there?

Answer 6

hopefully

Answer 7

Type what you got here afterwards.

Answer 8

sorry for asking alot but when you say (4/3) is that multiplying 4 x 3

Answer 11

so im doing 4 divided by 3 multiplying it 2.8 x 2.8 x 2.8 and thats the answer?
cause i got 2926.33333333333

Answer 12

Answer 13

oh, is that the answer or do i have to multiply/ add 3.14

Answer 14

THe second one is the correct answer with π multiplied to it.

Answer 15

ohhhhhh! (: thanks it makes sense now

Answer 16

do i do that for the rest of them?
