Answer 1

Answer:

arc = 15π

Step-by-step explanation:

The arc is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × $\frac{225}{360}$ ( r is the radius )

given diameter = 24 then r = 24 ÷ 2 = 12

arc = 2π × 12 × $\frac{5}{8}$

     = 24π × $\frac{5}{8}$

     = 3π × 5

    = 15π
