Answer:
The answer is 2pi
Step-by-step explanation:
To find the area of a cirlce, use the equation ( pi * r^2 ) so for a semi circle, which is half, simply divide that by 2. Plug in 2 for radius and you get 4pi/2 which simplifies to 2pi.
Answer:
An Acute triangle
Step-by-step explanation:
An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°).
Answer:
1/3 of 45 = 15 cubic feet
Step-by-step explanation:
volume of rectangular prism = (B)(h)
volume of rectangular pyramid = 1/3(B)(h)
<h3>How can she find the coordinates of the new point without graphing the point?</h3>
- If you know the coordinates of any two points on a straight line, you can compute its slope without looking at its graph. Every point has two coordinates: an x-value and a y-value, which are expressed as an ordered pair (x, y). The x value indicates the horizontal location of a point.

This is overdetermined. Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:
Answer: A=35°, C=90°, B=55°
We can do it the way they like.
7+18+11 =36
so to get 180 degrees we need to scale the ratio elements by a factor of 5.
7:18:11=35:90:55
A is the smallest. We see C is indeed a right angle and B is complementary to A.
