Meka plans to bake a large circular cookies for her brothers. She wants to decorate the outer edge of the cookie small pieces of choclate. The radius of the cookies is 7 inches.What would be the closest to the curcumference of the cookie?
circumference = 2πr
= 2π(7) = 14π
That is the "exact" value of the circumference.
To find the circumference of a circle, you use the formula: C = 2πr, where C is the circumference and r is the radius.
In this case, the radius of the cookie is given as 7 inches. Substituting this value into the formula, we get:
C = 2π(7)
First, let's calculate the value of π (pi). Pi is a constant value that is approximately 3.14, but it is best to use the more accurate value of π.
C ≈ 2 × 3.14159 × 7
Now, let's calculate:
C ≈ 43.9823
Rounding to the nearest whole number, the closest circumference of the cookie would be approximately 44 inches.
