Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:

Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that
is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find
:

This is given in radians, so
is 4 radians
D is the correct answer choice.

Answer:
Mr body took 9 blue pills
Step-by-step explanation:
Total number of pills consumed = 17
Number of blue pills, b = 11
Number of blue pills, b = g + 3
So that,
b = g + 3
11 = g + 3
g = 8
Total number of pills recommended = b + g
= 11 + 8
= 19
Total number of pills consumed = 17
Thus,
Number of blue pills consumed = 17 - 8
= 9
Therefore, Mr body took 9 blue pills.
The area of a triangle for one of the legs being 3 inches and the hypotenuse being 9 inches is 12.727 square inches
<em><u>Solution:</u></em>
Given that to find area of a triangle for one of the legs being 3 inches and the hypotenuse being 9 inches
From given information,
Let "c" = hypotenuse = 9 inches
Let "a" = length of one of the leg of triangle = 3 inches
To find: area of triangle
<u><em>The area of triangle when hypotenuse and length of one side of triangle is given:</em></u>

Where, "c" is the length of hypotenuse
"a" is the length of one side of triangle
Substituting the given values we get,


Thus area of triangle is 12.727 square inches
