What is the circumference of a circle with a radius of 3 inches? Use 3.14 for pie
2 answers:
Answer: 18.84
First, the formula utilized to find the circumference of a circle is C=2πr.
So, C=2x3.14x3
2x3.14= 6.28
6.28x3= 18.84
Answer:
18.85
Step-by-step explanation:
1. Formula for finding circumference is C=2πr.
2. Plug in the numbers. C=2(3.14)(3)
3. Multiply. 2 x 3.14 = 6.28 6.28 x 3 = 18.84
4. Answer is 18.84 (or 18.85 if rounding)

divide the numerator by the denominator
ex. 15 divided by 16
Step-by-step explanation:
180 degrees is half of a circle, and clockwise means turning in the direction a clock does - right.
So a point would be turned right halfway around.
f(x) = 20x² - 18x - 25
f(-1) = 20(-1)² - 18(-1) - 25
= 20 + 18 - 25
= 13
