Question

can someone please answer this question?

Answer 1

Answer:

254.34 mm²

Step-by-step explanation:

Diameter (d) = 18 mm

Radius (r) = d/2 = 18/2 = 9 mm

π = 3.14

Area of the circle

= πr²

= (3.14)(9)²

= 3.14 × 81

= 254.34 mm²

Answer 2

given:

diameter= 18mm

to find:

the area of the circle

solution:

$area = \frac{1}{4} \pi {d}^{2}$

$a = \frac{1}{4} \times \pi \times {18}^{2}$

$a = 254.469 \: {mm}^{2}$

hence, the area of the circle is 254.469 square millimeters.
