Answer: To find the cost to print a circular frame, we need to first find the area of circle.
Given:
We know that:
Area of circle
Also we are given cost per square foot is $27
Therefore, the cost to print a circular sign with a radius of 1.1 feet is:
or $102.58
Answer:
Step-by-step explanation:
The area of a triangle is given by
where
b is the base
h is the height
Here we have an equilateral triangle, which has the 3 sides of the same length.
Let's call L the length of one side.
We know that the perimeter of the triangle is
p = 9 in
The perimeter is the sum of the three sides, so:
Therefore, we find the length of the side:
Therefore the length is the base of the triangle,
The height can be calculated by considering half triangle: the hypothenuse is equal to L, while one side is equal to half the base (b/2), therefore the height is given by Pythagorean's theorem:
Therefore, the area of the triangle is:
