Question

1. the pizza’s crust has cheese in it. how many inches around is the crust if the diameter of the pizza is 4 inches (to the nearest hundredth)? options: 25.13 in, 13.00 in, 12.57 in, 6.28 in.

Explanation:

Step1: Recall the formula for the circumference of a circle

The circumference \( C \) of a circle is given by \( C = \pi d \), where \( d \) is the diameter of the circle.

Step2: Substitute the given diameter into the formula

We are given that the diameter \( d = 4 \) inches. Using the formula \( C=\pi d \), we substitute \( d = 4 \):
\( C=\pi\times4 \)

Step3: Calculate the value (using \(\pi\approx3.14159\))

\( C = 4\pi\approx4\times3.14159 = 12.56636 \)

Step4: Round to the nearest hundredth

Rounding \( 12.56636 \) to the nearest hundredth gives \( 12.57 \).

Answer:

12.57 in
