Studdy Solution
STEP 1
Assumptions1. The area of a triangle is given by the formula , where is the base and is the height.
. The base and height of the triangles are given in the problem.
3. The area of a circle is given by the formula A = \pi r^, where is the radius and is approximately3.14159, but in this problem, we are told to use .
STEP 2
First, let's calculate the area of the first triangle. We can do this by plugging the given values for the base and height into the formula for the area of a triangle.
STEP 3
Now, plug in the given values for the base and height to calculate the area of the first triangle.
STEP 4
Calculate the area of the first triangle.
STEP 5
Repeat steps2-4 for the remaining triangles, plugging in the given values for the base and height for each triangle.
