The circumference, C, of a given circle may be calculated through the equation,
C = 2πr
where r is the radius.
Substituting the known values from the given in this item,
C = 2(π)(5 in)
<em>C = 10π in</em>
Thus, the answer is this item is the second choice.
30°
Here's why:
Using the well-known Pythagorian theorem we can reckon how long the hypotenuse is:
c^2=6^2+36*3 -> c=12
Knowing that sin(a)=a/c=6/12=0.5 the measure of the angle in degrees is 30°
Hope could help :)
Answer:-1/2
Step-by-step explanation:
16^x=1/4
(4^2)^x=4^(-1)
4^2x=4^(-1)
Base cancelled each other since they are the same
2x=-1
Divide both sides by 2
2x/2=-1/2
x=-1/2
Find the x and y intercepts or any other 2 points. (I advise you finding the y intercept though.)
then calculate for slope using:
y(2) - y(1)
________
x(2) - x(1)
The (2) and (1) are not exponents they are small numbers at the bottom of the numbers.
The slope is: 4
Answer:
m∠60
Step-by-step explanation:
30 + 90 = 120
180-120=60
