Can you please help with the following questons:

1. Duran was baking cookies. Each cookie had a circumference of 9.3 inches. About how many inches is the diameter of each of Duran's Cookies?
a. about 3 inches b. about 5 inches
c. about 6 inches d. about 27 inches

2. A circular building has a diamter of 60.52 feet. About how many feet is the circumference of the building?
a. about 31 feet b. about 124 feet
c. about 183 feet d. about 195 feet
Thank you

1.

Circumference = Pie X Diameter

9.3 = Pie x X
9.3 / Pie = X
= 3. so A

2. Use the same formula :)

About 3. So your anwser would be A.

1. To find the diameter of each of Duran's cookies, we need to use the formula for the circumference of a circle which is C = πd, where C represents the circumference and d represents the diameter.

Given that the circumference is 9.3 inches, we can rearrange the formula to solve for the diameter as follows:

9.3 inches = πd

To isolate d, we divide both sides of the equation by π:

9.3 inches / π ≈ d

To approximate the value of d, we can substitute an approximation for π. A commonly used approximation for π is 3.14.

Therefore, d ≈ 9.3 inches / 3.14 ≈ 2.96 inches.

So, the diameter of each of Duran's cookies is approximately 2.96 inches.

Looking at the answer choices, the best option is (a) about 3 inches.

2. To find the circumference of the circular building, we can use the same formula as before: C = πd. Given that the diameter is 60.52 feet, we can substitute these values into the formula:

C = πd = 3.14 * 60.52 feet ≈ 190.09528 feet

Rounding this to the nearest whole number, we get the circumference to be approximately 190 feet.

Looking at the answer choices, the closest option is (d) about 195 feet.
