The circumference of a circle measures 11.275 pi ft what is the measure of the diameter of this circle

Step-by-step explanation:

hello :

The circumference of a circle is : 2rπ  when 2r  the diameter

2r×3.14 = 11.725

2r = 11.725/3.14

2r =  3.73

Area of Figure; 10 units^2

Step-by-step explanation:

We can split this figure into a triangle and a trapezoid, the triangle with a base of 4 units, apparent height of 2 units, the right trapezoid with base lengths of 4 and 2 units, height of 2 units;

Area of Triangle ⇒ 1/2 * base * height = 1/2 * 4 * 2 = 4 units^2

Area of Trapezoid ⇒( ( base + base ) / 2 ) * height ⇒ ( ( 4 + 2 ) / 2 ) * 2 =  ( 3 )*2 ⇒ 6 units^2,

Thus by the Partition Postulate;

Area of Figure ⇒ Area of Triangle + Area of Trapezoid, 4 + 6 = 10 units^2,

Area of Figure; 10 units^2
