To find the circumference of a circle, we can use the formula:
Circumference, \( C = 2\pi r \)
where \( \pi \) is the constant Pi (approximately 3.14159), and \( r \) is the radius of the circle.
Given that the radius of the circle is 1.4 inches, we can plug this value into the formula:
\( C = 2 \times \pi \times 1.4 \)
Let's now calculate this:
- First, multiply the radius by 2: \( 1.4 \times 2 = 2.8 \)
- Then multiply that result by the value of Pi: \( 2.8 \times \pi \)
By performing the multiplication, we find that the exact circumference of the circle is approximately 8.79645943005142 inches.
To present the circumference to the nearest tenth, we look at the hundredth place, which is 9 in this case. Since 9 is greater than or equal to 5, we'll round up the tenth place by 1.
As a result, when rounded to the nearest tenth, the circumference of the circle is approximately 8.8 inches.
