Question

Please help!!!!!!!!!!will medal and fan

Find the following measure for this figure.



Volume =

275 cubic units
91 2/3 cubic units
36 2/3 cubic units

Answer 1

You will use this formula

\[\Large V = \frac{1}{3}\pi*r^2*h\]

where

r = radius
h = height
pi is approximately 3.14

Answer 2

oh um

Answer 3

still confused

Answer 4

do you see how r = 5 and h = 11 ?

Answer 5

ya

Answer 6

so plug them in the formula

Answer 7

so 5 times 5 ti,es 11?

Answer 8

Yes correct
\[\Large V = \frac{1}{3}\pi*r^2*h\]
\[\Large V = \frac{1}{3}\pi*5^2*11\]
\[\Large V = \frac{1}{3}\pi*25*11\]
Do you see how to finish up?

Answer 9

no sorry i dont

Answer 10

25 times 11 = 275

then you multiply 275 by 1/3 to get ???

Answer 11

something with the fraction right?

Answer 12

ummm 91.6

Answer 13

now multiply that with the value of pi, which is approx 3.14

Answer 14

oh wait, are there pi symbols in your answer choices?

Answer 15

ya

Answer 16

turns out that \[\Large 91.\bar{6} = 91 \frac{2}{3}\]

Answer 17

ohh

Answer 18

so

\[\Large V = \frac{1}{3}\pi*25*11\]
\[\Large V = 91.\bar{6}\pi\]
\[\Large V = 91 \frac{2}{3}\pi \]

Answer 19

Another way to get 91 & 2/3 is to do

275/3 = 91 remainder 2

The 91 is the quotient
The remainder of 2 forms the numerator over 3

Answer 20

oh okay thank you!!!
