A. π6 B. π9 C. π12 D. 9π √3 E. 18π √3
Any quick way of doing this? OA not available
yep, kanwar86 is right..
please check your question again
This is what the question says, this was given to me by a friend so yes, source is not a standard one
The answer to this question, considering area of equilateral triangle to be 93, is 124π/√3
Approach:
1) Find altitude of equilateral triangle.
2) Centroid divides the altitude (median) of equilateral triangle in the ratio 2:1 with the larger part towards the vertex.
3) Larger part, found in step 2, is the circumradius from which area of circumcircle can be calculated.
