Answer:
201.06
Step-by-step explanation:
This is because the formula of the area of a circle is A=(pi)(r) squared
Since the radius if half of the diameter, the radius would then be 8.
8 squared, or 8 x 8 = 64.
64 times pi (64 x 3.14159)= 201.06
Answer:
15
Step-by-step explanation:
there are 2 red marbles for every 5 blue marbles, and we know that there are 6 red marbles total.
2x3=6, so we know that there are 3 sets of 2 red marbles, meaning there is also 3 sets of 5 blue marbles.
So there are 3x5=15 blue marbles in the bag
Prob ( a tail in one toss) = 1/2
Prob( 3 tails in 3 tosses) = 1/2 ^3
= 1/8 (answer)
60 degrees, hope this helps
