Answer:
616 cm²
Step-by-step explanation:
To find the area of a circle you use the formula A = π · r²
So we know that the diameter is 28 cm, to find the radius we would divide this in half, because d = 2r, giving us 14. Now we can do 14² which is 196, and then times that by pi or in this case 22/7.
196 × (22/7) = 616
<span>Answer is C.
Explanation :-
Take the 1st case where Number of student(n) = 3 and Cost per student(c) is 24, we get n*c = 72
Take the 2nd case n = 6 and c =12, we get n*c = 72
Take the 3rd case n = 9 and c = 8, we get n*c = 72
By above observation we can say that product of Number of student and cost per student is 72 always.
Now for n = 12 we have to calculate c
n*c = 72
c = 72/12 = 6.
hence answer is option C.</span>
