Answer:C) x2 + y2 =45
Step-by-step explanation:
The equation of a circle in standard form is (x-h)2+(y-k)2=r2.
Since you know the center is (0,0), you can sub this is value in for h and k, then use the point (3,6) to sub in for x and y and you will find r2 =45. Hope that helps :)
The circumference of a circle with a radius of 12 cm is 75.45 cm
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The circumference of a circle is given by:
Circumference = 2π * radius
Hence:
Circumference = 2(22/7)(12) = 75.45 cm
The circumference of a circle with a radius of 12 cm is 75.45 cm
