Answer: Probability of getting one volcano in the world on which to conduct an extensive study is 
Step-by-step explanation:
Since we have given that
Number of cinder cone volcanoes = 13
Number of shield volcanoes = 18
Number of stratovolcanoes = 6
Total number of volcanoes is given by
So, Probability of selecting one volcano in the world on which to conduct an extensive study is given by
Hence, Probability of getting one volcano in the world on which to conduct an extensive study is

Answer:
Step-by-step explanation:
9.65-9.56=0.09
0.09/9.56=0.009414
0.009414*100=0.94%
9.56 increased by 0.94% to 9.65
Diameter = 2r
6 = 2r r = 3 for the radius of the flowerbed
If we were to include the sidewalk around the bed, the diameter would stretch out another meter in both directions, meaning adding 2 meters to the diameter making the new diameter 6 + 2 = 8 and 8/2 = 4 so 4 = radius of the circle including the sidewalk. Find the area of the big circle and subtract the area of the smaller circle to find the area of the sidewalk.
Small circle = pi*3 squared.
