Verified Answer :

Step-by-step explanation:

Let's address each part of the problem:

C. Find the radius of the cylinder:

The formula for the cross-sectional area (\(A\)) of a cylinder is given by:

\(\[ A = \pi r^2 \]\)

Given that the cross-sectional area \(A\) is \(40 \, \text{cm}^2\) and the height \(h\) is \(5 \, \text{cm}\), we can rearrange the formula to solve for the radius \(r\):

\(\[ 40 = \pi r^2 \]\)

\(\[ r^2 = \frac{40}{\pi} \]\)

\(\[ r = \sqrt{\frac{40}{\pi}} \]\)

\(\[ r \approx 3.183 \, \text{cm} \]\)

So, the radius of the cylinder is approximately

\(\(3.183 \, \text{cm}\).\)

B. Find the length of side BD:

Without a diagram or further context, it's challenging to determine side BD. Could you provide more information or clarify the context?

14. Find the area of the wheel:

To find the area of the wheel, we need to know the formula for the area of a circle, which is:

\(\[ A = \pi r^2 \]\)

Given that the radius

\(\(r\) is \(6 \, \text{\)
