I don't know if your school lets you simplify pi so I'll put two options;
here's simplified pi.
Step 1; Write Out Your Problem
A =

x 8^2
Step 2; Simplify 3.14 for

A = 3.14 x 8^2
Step 3; PEMDAS/Solve for 8^2
A = 3.14 x 64
Step 4; PEMDAS/Multiply 3.14 by 64
A = 200.96
Step 5; Simplify
In this case you don't need to simplify.
And here's the un-simplified pi;
Step 1; Write Out Your Problem
A =

x 8^2
Step 2; PEMDAS/Solve for 8^2
A =

x 64
Step 3; PEMDAS/Multiply pi by 64
A = 201.06192983
Step 4; Simplify
A = 201.06
It will take approx. 22 minutes and 30 seconds for the speeches.
<h3>What is Division?</h3>
It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.
Here, Time duration of each learner = 1 minutes 30 seconds
= 3/2 minutes.
Total number of learners = 15
Time taken by all the speech category = 15 X 3/2
= 45/2
= 22 minutes 30 seconds
Thus, It will take approx. 22 minutes and 30 seconds for the speeches.
