Use cross multiplication. The ration of length to width is 6 to 1. The actual dimensions are 30 to x. Set them equal to each other and cross multiply. X (width) should come out to 5.
Answer:
The answer is 9.4 cm.
Step-by-step explanation:
To solve for the circumference of the circle, use the circumference formula, which is C = 2
.
Next, in the problem, the circle has a diameter measure but no radius measure. To find the radius of this circle, divide the diameter (3 cm) by 2, and it will equal 1.5 cm. The radius is being divided by 2 because the radius of any circle is equal to half the diameter of the circle.
Then, plug in the information given from the problem into the formula, and the formula will look like C = (2) (
) (1.5 cm).
Finally, solve the equation, and the answer is 9.4 cm.
