The answer for this Q is 3%
The answer is 4pi because the formula to find the circumference is C = 2 pi r. this question is asking for the terms of pi which means you remove the pi from the formula and solve it with out it. the radius is 2 because of the 2 units on the graph is halfway of the circle. you would just multiply 2 x 2 and get 4. after that you put the pi on the end of the 4. so the answer is C. (4pi)
Answer: I know the answer is 75 units but I’m not sure who’s right
Step-by-step explanation:
This is a 45-45-90 triangle. The side facing the 90 degree angle would be the a square root 2. The sides facing the 45 degree angles would be a. 2 square root 2 is facing a 45 degree angle, so that means the side facing the 90 degree angle would be 2 square root 2 x square root 2 which is 4. Basically:
a = 4
b = 2 square root 2
