Answer: A. 30
Step-by-step explanation:
The formula for the area of a circle is pi*r^2, where r is the radius of the circle.
900pi = pi*r^2
Divide both sides by pi.
900 = r^2
Square root both sides.
r = +/- 30.
Since the radius cannot be negative, the answer is 30 units.
counter clockwise would be rotating it up to the right.
C is 4 spaces away from A ,
A is on X3 & Y3 so 4 +3 = 7
so it would be x7 & Y3 so (7,3), the first answer
Answer:
15
Step-by-step explanation:
This is simply just 5 x 3 = 15
Hello!
As you can see, 22 is the opposite angle. We are looking for the adjacent angle. Let's just call it x. Using SOH CAH TOA, we see that the tangent is the opposite divided by the adjacent side. Let's use that.
tan54≈1.38
This gives us the equation below.
1.38=22/x
Let's solve this equation for x.
1.38x=22
x=22/1.38
x=15.94
Therefore, the length of the shadow is about 15.94 meters.
I hope this helps!
