Sean used candle molds, as shown below, to make candles that were perfect cylinders and spheres:
abruzzese [7]
56.52 in^3

V(cylinder) = pi * r^2 * h
V = pi * 3^2 ^ 6
V = pi * 9 * 6
V = 54pi

V(sphere) = (4/3) * pi * r^3
V = (4/3) * pi * 3^3
V = (4/3) * pi * 27
V = 36pi

54pi - 36pi = 18 pi
18 * 3.14 = 56.52

Solve this please show your work <3
Nookie1986 [14]

Given:

The expression is

\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=

To find:

The simplified form of the expression.

Solution:

We have,

\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=

The expression \sqrt[3]{48} can be written as

\sqrt[3]{48}=\sqrt[3]{8\cdot 6}

\sqrt[3]{48}=\sqrt[3]{8}\cdot \sqrt[3]{6}       [\because \sqrt[3]{ab}=\sqrt[3]{a}\sqrt[3]{b}]

\sqrt[3]{48}=2\cdot \sqrt[3]{6}

\sqrt[3]{48}=2\sqrt[3]{6}

Therefore, \sqrt[3]{48}=\sqrt[3]{8\cdot 6}=2\sqrt[3]{6}.
