Answer:
46
Step-by-step explanation:
4 x 2= 8
3 x 5= 15
2(8 +15)= 2(23)=
23 x 2= 46
Explanation
Step 1
We know that the general equation for a circle is
where
(h,k) is the center of the circel
and r is the radius
then, all we need to do is replace
Let
replace the values
therefore, the answer is
I hope this helps you
If we draw a perpendicular line from one of the vertices of the triangle we get 2 right angled triangles each with altitude 9 ins and vertex angle = 30 degrees. So:-
cos 30 = 9 /h where h = one of the sides of the equilateral triangle
h = 9 / cos 30 = 10.392 inches
Therefore the perimeter of the triangle = 3 * 10.392 = 31.1769 ins
Answer is 31.18 inches to the nearest hundredth.
