Two candles of equal heights but different thickness are lighted. The first burns off in 2 hours and the second in 5 hours. How long after lighting the both, will the first candle be half the height of the second?
Find the area of the triangle formed by joining the midpoints of the sides of the triangle whose vertices are ^@ A(8,-4)^@, ^@B(4,4)^@, and ^@C(12,8)^@.
A chord of a circle of radius ^@ 42 \space cm ^@ subtends a right angle at the center. Find the area of the corresponding major segment.^@ \bigg[\pi = \dfrac { 22 } { 7 }\bigg] ^@
There is a cylindrical pen holder of height ^@ 10 \space cm^@ and diameter ^@ 13 \space cm^@. Now the pen holder is cut into two pieces such that the height of the new pen holder is reduced to ^@ \left(\dfrac{ 3 }{ 5 } \right)^{th} ^@ of the height. The diameter of the new pen holder remains the same. If the new pen holder is filled with water up to the brim, then find the amount of water held in liters. (Where ^@ \pi = 3.14 ^@)
