Answer:
The circumference of the circle is 28.26 m.
The area of the circle is 63.585 
.
Step-by-step explanation:
To solve for the circumference of the circle, start by using the circumference formula of a circle, which is 
. However, 3.14 will be used instead of 
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 
. Then, solve the equation, and the answer will be 28.26 m.

Answer:iStep-by-step explanation:
i^42
In the equation mx+b, change m, since the variable m represents the slope of the line.
Step-by-step explanation:
a) The circumference of a circle is 360 degrees. so:
7x+15+8x+6x+30=360
21x+45=315
21x=135
x=<u>15</u>
b) This means 7(15)+15=120, 8(15)=120, and 6(15)+30=120. Thus, by the inscribed angle theorem, all the angles measure 60 degrees, and the triangle is thus <u>equilateral</u> and <u>isosceles</u>.
