I knew there was a formula for this, but did not remember it and so had to look it up. The formula is:

A = pi*r*(r + sqrt(h^2+r^2) )

Here, A = 3.14(4 ft)(4 ft + sqrt(36 + 16) = 140.9 square feet.

When in doubt about a formula, look it up!

The function d(h)=50+45hd(h)=50+45h represents the distance a family traveled, in miles, h hours after they stopped for lunch.

Anna [14]

<span>Given the function d(h)=50+45 represents the distance a family traveled, in miles, h hours after they stopped for lunch. The value 45 represents the speed they are traveling in miles per hour. So if the function will be graph, the 45 represents the slope of the line.</span>
