So the area of a circle is pi times the radius squared.

A= pi*r^2

The radius here is the diameter divided by 2.

radius = 16/2

r = 8

A= 3.14*(8)^2

A= 3.14*64

A= 200.96

C. 200.96 in^2

I see what you did wrong. You used the exact value of pi that the calculator gave you whereas the problem told you to estimate the value to 3.14 only. So you did it right, but the problem asked you to estimate the value of pi.

Hope this helps :)

You need to understand what the concept behind this problem is. Usually, in a triangle, adding measures and setting the sum equal to 180 is done when you know the measures of the 3 angles of a triangle since the sum of the measures of a triangle equals 180. Here, the expressions are the lengths of two sides of two different triangles.

Here is what you need to know to solve this problem.

First, here's a definition:

A midsegment of a triangle is a segment that has as endpoints the midpoints of two sides of the triangle.

Look at the big triangle above. The left side is separated into two congruent segments. The point in the middle is the midpoint of that side. The right side of the big triangle is also separated into two congruent segments. The point in the middle is the midpoint of that side. The segment labeled x + 5 is a midsegment of the large triangle since it joins the midpoints of two sides of the triangle.

Here is a theorem about the midesgment of a triangle.

The midsegment of a triangle is a segment that has as endpoints the midpoints of two sides of a triangle. The midsegment is parallel to and half the length of the third side of the triangle.

The part you need is "The midsegment is parallel to and half the length of the third side of the triangle." The midsegment that measures x + 5 is half the length of the segment that measures 3x - 1. Now we can write an equation and solve for x.

Multiply both sides by 2.

Subtract 3x from both sides. Subtract 10 from both sides.

Multiply both sides by -1.

There you have x = 11 which as you know is the correct answer, and now you know why. Please ask any questions if it is not clear.

200.96

Step-by-step explanation:

Diameter of the circle = 16 inches

Radius of the circle = 16/2

= 8 inches

pi = 3.14

Then

Area of the circle = pi (Radius)^2

= 3.14 * (8)^2

= 3.14 * 64

= 200.96 square inches

You need to swap the x values around. They need to be given in the same order as the y values. The sum should be:
