A circle has a radius of 12 cm. If the radius of the circle is increased by a factor of 7, how many times larger will the circle's circumference be?

The circumference is also 7 times larger

12 cm radius :2*pi*12= 75.43

12*7=84

84cm radius: 2*pi*84= 528

To check if its indeed 7 times larger: 528/75.43 and you'll get 7

If youre looking for the difference between the two: 528-75.43= 452.57

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
