## anonymous one year ago Sonja bought a 14-inch pizza. How much crust is around its edge? (Use 3.14 for pi.) 21.98 in. 43.96 in. 47.74 in. 87.92 in.

okay

2. anonymous

so, do you know the equation pi times diameter

3. anonymous

and then you would multiply 3.14 by 14

4. Michele_Laino

the measure of the length of the edge, is given by the subsequent formula: $\Large L = \pi D \cong 3.14D$ where D is the diameter of your pizza, namely D= 14 inches

3.14*14=43.96

6. anonymous
