Question

use a two - dimensional model and the dimensions provided to calculate the circumference and area of the flower. round to the nearest tenth, if necessary.

Explanation:

Step1: Find radius

Given diameter $d = 5$ in, radius $r=\frac{d}{2}=\frac{5}{2}=2.5$ in.

Step2: Calculate circumference

Circumference formula is $C = 2\pi r$. So $C=2\pi(2.5)\approx 15.7$ in.

Step3: Calculate area

Area formula is $A=\pi r^{2}$. So $A=\pi(2.5)^{2}\approx 19.6$ in².

Answer:

Circumference: 15.7 in, Area: 19.6 in²
