Answer:
The diameter was 
in.
Step-by-step explanation:
The arc of a circle is given by
where
s = arc length
r = radius of the circle
θ = measure of the central angle in radians.
From the information given
s = 4 in
θ = 32º
To find the diameter of the original pizza, we use the formula of the diameter of a circle
First, we need to convert the angle to radians
Next, solve for r from the arc formula
Then, we use the diameter of a circle formula
First find the product of 1.36 and 15
1.36×15=20.4
5,300.012+20.4= 5,320.412

First, you add up the total number of students because we would base our percentage one this.
Total number of students = 1+4+5+10+20+10+5
Total number of students = 55
Now, let's count how many of them got a score of more than 70. For this, you would only count the students belonging to 70-under 80, 80-under 90 and 90-under 100.
Students who got more than 70 = 20+ 10 + 5 = 35
Therefore the percentage is equal to:
Percentage = 35/55 * 100 = 63.64%
