Final answer:
To find the radius of a circle with a circumference of 330 cm using π as 3.14, divide the circumference by 2π to get the radius, which is approximately 52.55 cm.
Step-by-step explanation:
To find the radii of the circles with a given circumference of 330 cm using π (pi) as 3.14, you would use the formula for the circumference of a circle which is C = 2πr, where C is the circumference and r is the radius.
You know that C is 330 cm and you were told to use x (pi) as 3.14, so the equation to find the radius (r) becomes:
330 = 2 × 3.14 × r
To solve for r, you would divide both sides of the equation by 2π:
r = ÷(330 / (2 × 3.14))
Now, you can calculate the radius:
r = 330 / 6.28
r = 52.5477707 cm
However, because the original data (circumference) likely doesn't have that many significant figures, we would round our answer accordingly.
Thus, the radius of the circle is approximately 52.55 cm.
