An architect is designing a circular opening 16 feet in diameter to make room for a spiral staircase. if pi = 3.14, what will the circumference of the circular opening be?

50.24 feet

Step-by-step explanation:

Circumference of a circle is given by :-

, where d is the diameter of a circle.

Given : An architect is designing a circular opening 16 feet in diameter to make room for a spiral staircase.

i.e. d= 16 feet

Now, circumference of the circular opening will be :-

Hence, the circumference of the circular opening= 50.24 feet

the answer is 13/48

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
