49 pieces
First you change the foot into inches, so it is 1200
then you divide so it is 1200/ 24 3/8 = 49 3/13
but the remaining doesn't count since it is not one whole piece
Answer:
arc = 15π
Step-by-step explanation:
The arc is calculated as
arc = circumference of circle × fraction of circle
= 2πr ×
( r is the radius )
given diameter = 24 then r = 24 ÷ 2 = 12
arc = 2π × 12 × 
= 24π × 
= 3π × 5
= 15π
The value of c is 81/64 for the expression a perfect square trinomial.

What is an Expression?</h3>
An expression can be defined as a mathematical statement that consists of variables, constants and mathematical operators simultaneously.
It is given that an expression
x² +9/4x +c is a perfect square polynomial
c =?
(a+b)² = a² +2ab+b²
2ab = 9/4
b = 9/8
c = b² = 81/64
Therefore the value of c is 81/64 for the expression a perfect square trinomial.
