3.7 or 3 7/10

Because you need to make these mixed numbers into improper fractions.

Multiply the denominator by the whole number

5 × 8 = 40

Step 2

Add the answer from Step 1 to the numerator

40 + 4 = 44

Step 3

Write answer from Step 2 over the denominator

Find the volume of the composite solid. Round your answer to the nearest tenth.

EastWind [94]

Answer:

646.04 cm³

Step-by-step explanation:

Cube volume formula:

V=l*w*h

V=8*8*8

V=512

Hemisphere volume formula:

V=(4/3πr³)1/2

V=(4/3π4³)1/2

V=128/3

Add both together

128/3 + 512 ≈ 646.04cm³

A cylinder has a volume of 360 in^3. If the height and radius are multiplied by 2.5, what will the resulting volume be?

4vir4ik [10]

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=2.5r\\
h=2.5h
\end{cases}\implies V=\pi (2.5r)^2(2.5h)
\\\\\\
V=\pi \cdot 2.5^2\cdot r^2\cdot 2.5h\implies V=(2.5^2\cdot 2.5)\pi r^2 h
\\\\\\
V=15.625\pi r^2h\impliedby \textit{15.625 of the original}
\\\\\\
\textit{if the original was 360}\qquad 15.265\cdot 360$
