Question

The diameter of a circle is 34 yards. What is the circle's area? Use 3.14 for ​.

Answer 1

`907.43 \: {yrds}^(2)`

Explanation:

The formula to find the area of a circle is:

`\pi {r}^(2)`

since pi is 3.14 then, and the radius is half of the diameter, then:

`diameter = 34 \\ radius = (34)/(2) \\ radius = 17`

Therefore;

`area = \pi {r}^(2) \\ area = (3.14) {(17)}^(2) \\ = 3.14 * 289 \\ = 907.46 {yrds}^(2)`

Answer 2

907.46 mm2

Explanation:

Area of circle = (¶d^2)/4

d = 34 mm

Therefore

Area A = (3.14 x 34^2)/4

= 907.46 mm2
