Area

Since we know already know the rectangle's area and the length, we can use its Area formula to calculate its width:

\( A = lw\)

\( 28 = 7w\)

\(w = \cfrac{28}{7}\)

\(w = 4 \; [\text{m}]\)

Therefore, we can determine that the width of the rectangle is \(4 \; [\text{m}]\).

First, we need to determine the circle's radius, which is half the diameter:

Next, we can plug the radius into the circle's area formula to solve for its area:

\(A_{\text{Pizza}} = \pi r^2\)

\(A_{\text{Pizza}} = \pi (10)^2\)

\(A_{\text{Pizza}} = \pi (100) \)

\(A_{\text{Pizza}} = 314 \; [\text{in}^2]\)

Finally, to calculate the area of a single slice, we have to divide the whole pizza into \(16\) equal slices:

\(A_{\text{Slice}} = \cfrac{314}{16}\)

\(A_{\text{Slice}} = 19.625 \; \text{in}^2\)

Therefore, we can determine that the area of a slice of pizza is \( 19.6 \; [\text{in}^2]\). Tasty!
