Question

The worlds largest flower, the Rafflesia, has a circumference of 286 centimeters. Find the approximate diameter of the flower. Use 3.14 for pie. Round to the nearest hundredth if necessary.

Answer 1

Given:

The worlds largest flower, the Rafflesia, has a circumference of 286 centimeters.

To find:

The diameter of the flower.

Solution:

We know that, the circumference of a circle is:

$C=2\pi r$

Where, r is the radius.

$C=(2r)\pi$

$C=d\pi$                            $[\because 2r=d]$

Where, d is the diameter.

Putting $C=286, \pi=3.14$ in the above formula, we get

$286=d(3.14)$

$\dfrac{286}{3.14}=d$

$91.0828=d$

$d\approx 91.08$

Therefore, the diameter of the flower is about 91.08 centimeters.
