The length for the sides of the rug could be 4 feet, 4 feet, and 4 feet.
Answer:
We'll use 3.14 as an approximation of pi. So, now we plug the values into the equation. A = 3.14 * 8^2/2.
90 sides give us 90 angles
sum of all inside angels is (n-2) * 180 deg. where n is number of angels
so one inside angle is
(90-2)*180 deg / 90 = 88* 2 deg = 176 deg.
measure of exterior angle is 360 - 176 = 184 deg.
Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
An arc is a part of total circumference of circle and length of that arc is the measurement of linear distance.
Since we know the formula for "Length of an arc " , we get
Hence, Option 'C' is correct.
