If 80° ------> 88π cm
Then 360° ------> x cm
So:
x = (88π x 360) ÷ 80
x = 396 π (lenght of the circle)
The relationship of Lenght of circle and its diameter is:
L = d .π
replacing L:
396 π = d.π ----> d = 396 cm <---- here is your answer
Answer:
10 km/ hour = 6.25 miles/ hour
Step-by-step explanation:
cyclist travel in 5 hours = 6.25 x 5 = 31.25 miles
Answer:
B. substitute for X in first equation
