Answer:
pi x diameter
Step-by-step explanation:
To calculate the circumference of a circle, simply multiply pi (3.14) by the diameter (straight line passing from side to side through the center of the circle)
For instance, if you knew the diameter of a circle was 6 inches. Simply multiply 6 inches by pi!
6 x pi = ?
? approximately equals 18.85 inches.
The circumference of the circle would be 18.85 inches!
If you only have the radius of the circle, simply multiply it by two to get your diameter. Remember, the radius is just half the length of the diameter.
Hope this helps! :)
Answer:
x = 3.9
Step-by-step explanation:
So the whole angle PQS = 111 degrees
it gave you part of it so subtract that off . 111 - 72 = 39 degrees
10 times what equals about 39 degrees.
39/ 10 = 3.9

Answer:
AC=16.2 units
Step-by-step explanation:
we know that
The triangle ABC is an isosceles triangle
so
AX=XC
because triangles ABX and CBX are congruents
AC=2*AX
see the attached figure to better understand the problem
therefore
AC=2*8.1=16.2 units
