Answer
During squre root, you add 00 but you added only one decimal point in quotient why? I know tha this question is stuff but we topper sometime stuck on small problems it is a basis because we are human..

Answer
You made a mistake in Q21. While finding equation of PQ by using y=mx c and substituting value -3/2 in m. The equation must be 3x 2y-2c=0. But your equation was 3x 2y-c=0. The answer with both the equations is same but it confused me.
a chord AB of a circle, with centre O and radius 10 cm subtends a right angle at the centre of the circle. Find the area of the minor segment AQBP. Hence find the area of major segment ALBQA. (use π = 3.14)
there are two concentric circles of radii 6 cm and 4 cm with centre O. If AP is a tangent to the larger circle and BP to the smaller circle and length of AP is 8 cm, find the length of BP.
