Answer:
There are two sets of degrees going in opposite directions along an arc. The top of the arc shows degrees from 0º to 180º from left to right. The bottom of the arc shows degrees from 180º to 0º from left to right. The smallest "tick marks" along the edge of the protractor represent 1º intervals.
Step-by-step explanation:
The time he spent running is 13.80 seconds.
<h3>
How much time did he spend running?</h3>
The equation that can be used to represent the time he gets to the tree is:
Time he gets to the tree = (time of each spin x total spins) + time he spent running
21 = (6 x 1.2) + r
21 = 7.20 + r
r = 21 - 7.20
r = 13.80 seconds

Answer:
1246 yards
Step-by-step explanation:
To find the yard of fencing she needs for he cows, we simply need to find the perimeter of the rectangular area.
The area is 200 yards by 423 yards.
The perimeter is the sum of all the sides of a rectangle and it is given by:
P = 2(L + B)
P = 2(200 + 423) = 2(623)
P = 1246 yards.
She needs 1246 yards of fencing.
Answer: 0.539 cubic decimeters of blood can be hold by the cylinder.
Step-by-step explanation:
Volume of cylinder= volume of blood it can hold = 
Given :
Height of cylinder (h) = 9.5 cm
Diameter of cylinder (d) = 0.85 cm
Thus radius of cylinder (r) = 
Putting the values we get:
Volume of cylinder= volume of blood it can hold = 
[tex] (1cm=0.1dm)
Thus 0.539 cubic decimeters of blood can be hold by the cylinder.
Since AB if of the whole circumference, which covers 360 degrees.
So in radian, it's 2pi
