Question

A cone has a base that is 12 1/2 cm2 and a height of 10 cm. what is the volume

Answer 1

do you know the formula?

Answer 2

\(\large\dfrac{πr^2h}{3}\)

Answer 3

but i don't know the radius

Answer 4

your welcome

Answer 5

do you by chance have any answer choices?

Answer 6

no i do not

Answer 7

ok now the base is a circle
the formula for that is
\(\large{πr^2}\)

Answer 8

the total base is 12.5
so divide 12.5/3.14

Answer 9

39.25

Answer 10

thanks

Answer 11

12.5/3.14 = 3.98
now find the \(\large\sqrt{3.98} = 1.99~which~can~be~rounded~to~2 \)

Answer 12

now use the formula for the volume of the cone
