Question

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

Answer 1

Answer:

907.46 mm2

Step-by-step explanation:

Area of circle = (¶d^2)/4

d = 34 mm

Therefore

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

= 907.46 mm2

Answer 2

$907.43 \: {yrds}^{2}$

Step-by-step 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:

$diameter = 34 \\ radius = \frac{34}{2} \\ radius = 17$

Therefore;

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