Question

Calculate the surface area and volume of a spherical ball that has a 2 inch diameter

Answer 1

SA= 4 pi r^2
V= 4/3 pi r^3

Answer 2

what s the radius though

Answer 3

radius is half of you diameter

Answer 4

1

Answer 5

yep

Answer 6

so is the answer sa=157.75

Answer 7

no

Answer 8

SA I got is 12.6

Answer 9

i must be doing something wrong

Answer 10

3.14*4

Answer 11

Answer 12

4.18

Answer 13

how are your aswers supposed to be? in terms of pi?

Answer 14

good question

Answer 15

i think so

Answer 16

the 12.6 was right

Answer 17

oh so to find the volume just muliply 4/3 by pi

Answer 18

1 to and positive power is 1 so you dont need to worry about anything but the pi

Answer 19

ok so i got4.18

Answer 20

yep

Answer 21

\[4\pi = 12.5664 \text{ and } \frac{4}{3}\pi =4.18879 \]
