The circumference of the circle is found using the formula C = 2 PI r
Circumference = 2 *PI * 15.5 = 31pi
The angle is 90 degrees, which is 1/4 of a complete circle ( 360 degrees).
The arc length would be 1/4 of the circumference:
Arc length = 31pi / 4 = 7.75PI
7/8 is a answer of this question
Answer:
3.26 hours
Step-by-step explanation:
speed = distance / time
595 = 1940 / t
t = 1940 / 595 = 3.26 hours
or
there is an error because -9 x 1 = -9 not -1. But I would assume that you multiply -9×-1 and then -9×-2 ect.
228 - 48 = 180
180/48 = 3.75
Its increase 375%
