Answer: 12 square units
Step-by-step explanation: first you must count hom many units there are between points A and B, which is 4, and then count the points between B and C, which is 6.
Now that we have the units we do 6 x 4 = 24, however, you may be asking why we do not do 24 then, well if you were to be doing 6 x 4, you would be getting the area of a rectangle, and half of a rectangle is a triangle, so we have to do 24/2 which equals 12.

Answer:
0.905 in
Step-by-step explanation:
Parameters given:
Volume of cone, V = 3.6 in³
Height of cone, h = 4.2 in
Although the diagram is not shown, this problem can be solved.
The volume of a cone is given as:
V = ⅓ * π * r² * h
r is the radius of the base of the cone
We can find r.
3.6 = ⅓ * π * r² * 4.2
3.6 = 4.399 * r²
=> r² = 3.6 / 4.399
r² = 0.8184
=> r = 0.905 in
The radius of the base of the cone is 0.905 in.
Coordinates of point A are
(-3,-2)
Origin lies in the center of coordinate system. That means that you can picture this as right triangle with sides 3 and 2 and you need to find hypotenuse of it.
Using pythagoras theorem we calculate:
h^2 = 3^2 + 2^2 = 13
h = sqrt 13

Both base and height of the sail is 40 1/2 feet.
A sail is triangular in shape. Finding the area of a triangle is multiplying its base and height and dividing the product by 2.
A = 1/2 bh
Area = 40 1/2 or 40.50 sq. ft
Since base and height are equal.
40.50 x 2 = 81
bh = 81
bh = 81 ÷ 2
b = 40 1/2 ft
h = 40 1/2 ft
