These are math problems. Find the area of the following figures. since i cant draw here we go.
1. Description: Circle has a line that line stops half way through and it has 16 in. written on top of the line.
2. Triangle has a line going from the bottom to the top point and has written 38 in. then there is a line under the triangle that says 32 in. what is the area?

1. That number is the radius of the circle.
The formula for area of a circle is pi x radius squared.
So the answer is 16 squared = 256 x pi inches squared. (you don't have to multiply in pi, as it's irrational)
2. The formula for area of a triangle is 1/2 x b x h. The height is 38, the base is 32. So just multiply 38 x 32 x .5 = 608 inches squared

the area of a circle is pie time the radius squared the radius is half the diameter (which is the full line going across the circle) but since it only goes half way it gives you the radius which is 16 in. and pie equals 3.14 so the equation is a(area)=3.14x16x16 which is 803.84 in.
the area of a triangle is 1/2 times the base times the hight the hight is the line going from the bottom of the triangle to the point which is 38 in and the base is 32 so the equation is a=1/2(32)x38 which is 608
