Question

Find the circumference of a circle with a diameter of 15 inches... Round to the nearest tenth and include units in your answer... SHOW WORK

Answer 1

47. 1

Explanation:

The equation for the circumference of a circle is C = pi X diameter.

Answer 2

47. 1 inches ; where inches ⇒ units

Explanation:

Consider the Circumference as such;

`Diameter - 15 inches,\\Circumference - 2\pi r, r - radius,\\\\2\pi r = \pi d, d - diameter ( considering, 2 * r = diameter )\\\\Circumference = \pi * d = \pi * diameter = \pi * 15 = ( About ) 47.1 inches\\Solution; Circumference = ( About ) 47.1 inches`

From this we can tell that ⇒ Answer; 47. 1 inches, where inches - units
