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
right.
To find the circumference of a circle, you need to use the formula C = πd, where C represents the circumference and d represents the diameter. In this case, the diameter is given as 16 feet.
Using the given value of π as 3.14, we can calculate the circumference as follows:
C = πd
C = 3.14 × 16
C ≈ 50.24 feet
Therefore, the circumference of the circular opening will be approximately 50.24 feet.
To find the circumference of a circle, you need to use the formula C = 2πr, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
In this case, the diameter of the circular opening is given as 16 feet. To find the radius, you divide the diameter by 2. So, the radius (r) of this circle will be 16 feet / 2 = 8 feet.
Now, using the formula C = 2πr, you can substitute the values to calculate the circumference:
C = 2 * 3.14 * 8
C = 50.24 feet
Therefore, the circumference of the circular opening will be 50.24 feet.
