find the radius of a circle whose circumfrence is 176 cm
28
To find the radius of a circle given its circumference, you can use the formula:
C = 2πr
Where:
- C is the circumference of the circle,
- r is the radius of the circle,
- π (pi) is a mathematical constant approximately equal to 3.14159.
In this case, you are given that the circumference (C) is 176 cm. So, you can rearrange the formula to solve for the radius (r):
r = C / (2π)
Now, substitute the given value of the circumference into the formula:
r = 176 cm / (2π)
Calculating this expression gives you the value of the radius.
C=π*d
d=diameter=2r
r=radius
176=π*d
divide both sides of the equation by π
176/π=d
take that answer and divide it by 2
Hope this helped :)
