Answer:
1. 68/89
2. 46/267
Step-by-step explanation:
1. The total number of people in drama or athletics can be found by adding up all categories where a person fits at least one of the criteria:
51+11+12+15+108+7=204
Now we need to add up the total number of people in all categories:
51+11+12+15+108+7+63=267
Finally, we divide the total number of people in either drama or athletics by the total number of people in all categories:
204/267 = 68/89
2. The total number of people in athletics and drama can be found by adding up all categories where a person fits both criteria:
15+12=27
The total number of people in music and athletics can be found by adding up all categories where a person fits both criteria:
7+12=19
Now, we add both of these numbers together and put it all over the total number of people:
27+19=46
46/267
So basically, what this question is asking you for is the surface area of the entire cone.
To find it, we can use the formula:
SA = 3.14*r*l+3.14*r^2, where r is radius and l is lateral height
Now, all we have to do is plug all of the given values into the equation
Therefore, the equation we get is:
SA = 3.14*1.5*5 + 3.14*1.5^2
If we simplify, we find that the surface area is equal to 30.615
If we round this number to the nearest whole number, we get 31 square inches
Therefore the answer is 31
