Answer:
10.5 cm^2
Step-by-step explanation:
Since we have two sides and the angle between those sides, we can use the alternative area formula:

a and b are the two sides while C is the angle in between the two sides.
Plug in the numbers:

Recall the unit circle. Sin(150) is 1/2.


I believe the answer is probability
Answer: Last Option is correct.
Step-by-step explanation:
Since we have given that
Number of yellow marbles = 8
Number of green marbles = 9
Number of purple marbles = 3
Number of red marbles = 5
So,
Probability that there is atmost one purple marble is given by

Hence, Last Option is correct.
Answer:
52.4 cm
Step-by-step explanation:
Circumference of a circle = 2πr
Radius, r = diameter / 2
= 17 cm / 2
= 8.5 cm
π = 3.14
Circumference of a circle = 2πr
= 2 × 3.14 × 8.5
= 53.38 cm
Approximately 52.4 cm
