The circumference of a circle can be found using the c = 2πr Find the circumference of a circle with a diaper of 4 ft

12.57

Step-by-step explanation:

2 π r d= 2 r

Solving for C

C= d = π 4 ≈12.56637

the answer is d. 75%

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
