Sometimes writing can be an issue. Finding inspiration can be difficult... Might I suggest... A mystery perhaps. Or a fantasy.
Answer:
15.7 km
Step-by-step explanation:
First find the circumference around the circle
C = 2*pi*r
C = 2 *3.14 * 10
62.8
Then find the fraction of the circle the arc is
The arc is 90 degrees and the circle is 360 degrees
90/360 = 1/4
Multiply the circumference by the fraction
1/4*62.8 =15.7
55/11 7*(2 14) 2 times 14 is 28
=55/11 7*28 55/11=5 7 times 28 = 196
=5*196=980
