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! :)
Face or base if you are looking for a word
In order to solve for the area of the triangle with the
given dimensions, we use the equation
<span> A
= ac(cos b)/2</span>
Substituting the known values,
<span>
A = (11 cm)(18 cm)(cos 104o)/2 = 23.95 cm2</span>
<span>Thus, the answer is the third choice. </span>
