The formula in computing the area of the circle is:
A = pi (r)^2
Where r = the radius of the circle
Since you are only given the diameter of the circle, you
have to solve for its radius. The radius of the circle is half its diameter. Therefore,
the radius of the circle is 5 (10/2).
Now, you substitute the measurements to the formula:
A = 3.14 (5)^2
A = 3.14 (25)
A = 78.5 sq. units
I'm pretty sure this is the answer:
(10)sin(40°) = AC
It's <em>sin </em>becasue it <em>needs </em>the opposite side of 40° and <em>has </em>the hypotenuse.
Use socratic to find your answer! :)
8800 yards is equal to five miles
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
