Question

1. ARCHAEOLOGY While digging a hole to plant a tree,

Hamad found a piece of a broken saucer. What was the
circumference of the original saucer? Round to the
nearest hundredth.

Answer 1

To find the circumference of the original saucer, use the formula 2πr, where r is the radius. Assuming the piece found is half of the saucer, multiply the given radius by 0.5 and substitute it into the formula to calculate the circumference.

Step-by-step explanation:

To find the circumference of the original saucer, we can use the formula:

Circumference = 2πr

Since Hamad found a piece of a broken saucer, we need to find the circumference of the whole saucer. Let's assume the piece Hamad found is half of the saucer, so its diameter (2r) is equal to the diameter of the saucer. We can then use the given radius to find the circumference:

Circumference = 2π(0.5r)

Once we have the value of r, we can substitute it into the formula to calculate the circumference.

Answer 2

2(pi)r

2(pi)0.75
Circumference is 4.71.
