Question

MEDAL & FAN ANYBODY ?
Calculate the volume of a sphere with a radius of 3 in. Express your answer in terms of π.
V = 36π in.3
a. 36π in.3
b. 45π in.3
c. 63π in.3
d. 81π in.3

Answer 1

V=4/3 pi r^3

Answer 2

V=4/3 (3)^3 pi
=4*9 pi=36 pi in^3

Answer 3

you are right A is the answer

Answer 4

\[4/3 \times \pi \times r^3\]

Answer 5

r is 3
\[4/3 \times \pi \times 3^3\]

Answer 6

\[3^3 = 3 \times 3 \times 3 = 9 \times 3 = 27\]

Answer 7

so now
\[4/3 \times \pi \times 27\]

Answer 8

now \[4/3 \times 27\]

Answer 9

so 3 times 9 is 27 so now
\[4 \times 9 \]

Answer 10

which is \[4 \times 9 = 36\]

Answer 11

therefore out of the options given A is correct
