Answer: side 1 = 4m, side 2 = 4m, side 3 = 3m

2 times 4 = 8
8 - 5 = 3

Perimeter of triangle = 4 + 4 + 3
P = 11 m

PLEASE HELPPPPPP FINDING CIRCUMFERENCE AND AREA OF A CIRCLE
11111nata11111 [884]

Answer:

The circumference of the circle is 28.26 m.

The area of the circle is 63.585 m^{2}.

Step-by-step explanation:

To solve for the circumference of the circle, start by using the circumference formula of a circle, which is C= 2\pi r. However, 3.14 will be used instead of (\pi) for this formula.

First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.

Next, plug in the radius into the formula, and the formula will look like C=(2)(\pi )(4.5 m). Then, solve the equation, and the answer will be 28.26 m.

To solve for the area of the circle, start by using the area formula of a circle, which is A=\pi r^{2}. However, 3.14 will be used instead of (\pi) for this formula.

For the area, plug the radius into the formula, and the formula will look like A= (3.14)(4.5m)^{2}. Then, solve the equation, and the answer will be 63.585 m^{2}.

What is the area of this shape
Tema [17]
This is the area of a trapezoid and the formula for that is:
.5(h)(b1 + b2) where h is height and b1 and b2 are the base length or the length of the parallel sides.  therefore, our area is:
.5(16)(6+12)
8(18)
144
if you're wondering why the area formula works, construct another trapezoid but this time upside-down.  now flip it along it's height axis so you can align one of the side lengths of the 2 trapezoids and you have a parallelogram.
the base of this parallelogram is b1+b2 of the original trapezoid and the height still remains h so the area of this parallelogram is (h)(b1 + b2).  however, we want to find the area of the trapezoid but we find that the parallelogram is twice the area of our trapezoid so the area of the trapezoid is half the area of the parallelogram.  so area = .5(h)(b1 + b2).
