The given circumference is C = 12*pi
The formula for the circumference of any circle, with radius r, is
C = 2*pi*r
Plug in the given value of C and solve for r
C = 2*pi*r
12*pi = 2*pi*r ... C has been replaced with 12*pi
12 = 2*r ... divide both sides by pi (they cancel out)
6 = r ... divide both sides by 2
So r = 6 is the radius
Answer:
there is only 3 solution for this equation
Step-by-step explanation:
I hope this is right!
The surface area of a prism is the sum of the lateral area plus the area of the two bases.
<span>LA = p * h </span>
<span>p is the perimeter of the base </span>
<span>For your prism </span>
<span>SA = 2(70) + 50 * 9 = 590 mm^2 <-----OPTION C
</span>
Hope this answers the question,
m^2-2mn+n^2 m=-2
(-2)^2-2*-2*4+(4)^2
=>4+16+16
=>36
Hope this helps u...!!!
