Answer 1

To find the probability you do 360/45= 8 to find that there are 8 pieces. Then you find what 1/8 is and that answer is .125 /.13. This means that it is either C or D.

The area is 14.1 since you crossmultiply central angle/360 * sector/pi r2 (36pi) so 45 * 36pi = 5089.38 and then you do sector * 360 which equals 360 only and then you take 5089.38/360 and get 14.1

Answer 2

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Diameter of the spinner = 12

Radius of the spinner = 6

We need to find the area of indicated sector.

As the measure of angle in that sector = 45°

So, Area of given sector would be

$\dfrac{\theta}{360^\circ}\times \pi \times r^2\\\\=\dfrac{45}{360}\times \dfrac{22}{7}\times 6\times 6\\\\=14.1\ sq.\ units$

Probability of spinning the color i.e. purple is given by

$\dfrac{1}{8}=0.125\approx 0.13$

Hence, Option 'd' is correct.
