<u>Answer:</u>

r =\bf 8 \space\ cm

<u>Step-by-step explanation:</u>

The formula for volume of a cylinder is as follows:

\boxed{Volume = \pi r^2 h}

where:

• r = radius (? cm)

• h = height (7 cm).

Substituting the values into the formula:
448 \pi  = \pi \times r^2 \times 7

Now solve for r:

⇒ r^2 = \frac{448 \pi }{\pi \times 7}

⇒ r = \sqrt{64}

⇒ r =\bf 8 \space\ cm

\huge\mathbb{ \underline{SOLUTION :}}

Given:

  • \longrightarrow\bold{Volume= 449 \pi cm^3}

  • \longrightarrow\bold{Height= 7cm}

\longrightarrow\sf{V= \pi r^2 h}

\longrightarrow\sf{448 \pi= \pi r^2 \cdot 7}

\longrightarrow\sf{448=7r^2}

\longrightarrow\sf{r^2=  \dfrac{448}{7} }

\longrightarrow\sf{r^2=64}

\huge \mathbb{ \underline{ANSWER:}}

\longrightarrow\sf{r= 8cm}
