@hartnn

Answer 2

AND the volume too!!

Answer 3

Answer 4

@Preetha

Answer 5

diameter = 7, so whats the radius ?

Answer 6

radius is half the diameter.

Answer 7

3.5

Answer 8

right , now surface area is \(\huge 4\pi r^2\)

Answer 9

49 pie?

Answer 10

yup, 49pi .....if u want answer without pi, u can put pi=3.14 or 22/7

Answer 11

with pie and for volume as well

Answer 12

Volume = \(\huge \frac{4}{3}\pi r^3\)

Answer 13

I got 42.875

Answer 14

i m getting 57.16 pi

Answer 15

57.16 pi cm^3

Answer 16

Oh...wait..

Answer 17

V = 4/3 * pi* (3.5)^3
SA = 4 * pi * (3.5)^2

Answer 18

I typed it in wrong, I got 57.16 too

Answer 19

then its correct
57.16 pi cm^3
to be complete....

Answer 20

V = (343/6) pi cubic centimeters
SA = 49 pi square centimeters
