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.

Step-by-step explanation:
Answer:
The slope is 0.3.
Step-by-step explanation:
1.5x + 4.5y = 18
<u>4.5y</u> = <u>18 - 1.5x</u>
4.5 4.5
y = 4 - 0.3x
X = 60 degrees.
A triangle is 180 degrees one side is 30 degrees, and another is 90(right angle)
180 - 30 - 90 = 60
It depends on if the ocean floor is cold or warm or freezing maybe below 0°
