How many cubic centimeters of water can this paper cone cup hold?

Igoryamba

Answer:

150.72 cubic centimeter

Step-by-step explanation:

Given:-

Height of cone (h) = 9cm

Diameter of cone(d)=8cm

radius of cone(r)= $\frac{d}{2}$ = $\frac{8}{2} =4cm$

To calculate= Volume of cone( $V_{cone}$ )

$Volume\ of\ cone(V_{cone}) =\frac{1}{3} \times \pi \times r^{2} \times h$

$=\frac{1}{3} \times 3.14\times 4^{2} \times 9$

Volume of cone( $V_{cone}$ ) $=150.72\ cubic\ centimeter$

Therefore paper cone cup can hold 150.72 cubic centimeter of water.

Step-by-step explanation:

${9}^{ \frac{3}{2} } \times {27}^{ \frac{1}{2} } = {(3)}^{ \frac{3}{2} \times 2 } \times {(3)}^{ \frac{1}{2} \times 3} \\ = {3}^{3} \times {3}^{ \frac{3}{2} } \\ = {3}^{3 + \frac{3}{2} } \\ = {3}^{4\frac{1}{2} } \\ = {3}^{ \frac{9}{2} }$
