Question

Work out the area of the circle below. Give your answer to 1 d.p. 16.3 cm​

Answer 1

To work out the area of a circle, we use the formula:

`\displaystyle\sf \text{Area} = \pi r^(2)`,

where
`\displaystyle\sf \pi` is a mathematical constant approximately equal to 3.14159, and
`\displaystyle\sf r` is the radius of the circle.

Given that the radius of the circle is 16.3 cm, we can substitute this value into the formula:

`\displaystyle\sf \text{Area} = \pi (16.3 \, \text{cm})^(2)`.

Calculating this expression, we have:

`\displaystyle\sf \text{Area} \approx 3.14159 * (16.3 \, \text{cm})^(2)`.

Simplifying further:

`\displaystyle\sf \text{Area} \approx 3.14159 * 265.69 \, \text{cm}^(2)`.

Rounding the result to 1 decimal place, the area of the circle is approximately 834.0 cm².
