Hello!The formula for circumference of a circle = π · d
π = 3.14
Diameter is equal to 37.68 ÷ 3.14
The diameter = 12
The formula for area of a circle = π · r²
![r = (1)/(2) d](https://img.qammunity.org/2019/formulas/mathematics/middle-school/7q9xsdowrx3swn1g7o5ytph7bdhg4hbbal.png)
12 ÷ 2 = 6
The radius is 6
6² = 6 × 6 = 36
36 × 3.14 = 113.04
The area of the circle is 113.04 units²
