The area of a triangle is determined by the formula: Base x Height * 1/2
You'll need to assign a base to the triangle. Based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). The distance between any two numbers is found by just subtracting them. Here, you should subtract the x values to find the distance of this side.
2 - (-2) = 4.
So the distance (aka the length of the base) is 4. The height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). We should subtract the y values this time to find the height/distance.
4 - 1 = 3
So the height is 3.
Base = 4
Height = 3
Answer:
volume = 25.1 m³
Step-by-step explanation:
volume = 1/3πr²h = 1/3(3.14)(2²)(6) = 25.1 m³
There you go. Depends on which value of pi you use.
A set of pencils sells for 1.75 and costs 0.40 to make
if 500 sets are sold...
500(1.75) = 875...this is revenue
500(0.40) = 200....this is expenses
profit = revenue - expenses
profit = 875 - 200
profit = 675
20% of the profit goes to the school...
0.20(675) = $ 135 <=== this is what goes to the school
