11. The central angle of an arc measures 12. The radius of its circle is 30 inches. What is the length of the arc to the nearest quarter inch?
A 1 in.
1
C 37
2
in.
B 6- in.
4
D 94.1 in
.
4

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

hi there!

the answer will be d: 2

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
