Answer:
23 inches
Step-by-step explanation:
Circumference = 2πr
72 = 2×3.142×r
Divide through by 2 × 3.142
r = 
r = 11.458 inches
Diameter = 2r
Diameter = 2* 11.458 = 22.92
= 23 inches to the nearest inch

angle a=20°
To Find:;
AC = ?
Solution:
Triangle sum property:
In a Triangle sum of the measures of all the angles of a triangle is 180°.

We know in a Triangle Sine Rule Says that,
In Δ ABC,

substituting the given values we get


Therefore,

Answer:
