Replyin Q 6 (b)

Replyisnt ABCD a cyclic quadrilateral?

and isnt angle ADC=180-100=80 (as opposite angles of cyclic quadrilaterals

are supplementary)

and isnt angle DCT=angle CAD as interior opposite angles due to tangent properties

SO WHY THE RADIUS AND OTHER ANGLES IF YOU COULD FIND THE REQUIRED ANGLES OUT IN SIMPLER METHODS INSTEAD OF BREAKING YOUR HEAD OVER IT??

It is a cyclic quadrilateral

Replyquestion 7 (b) de answer is supposed to be 90 (i checked a few solved textbooks and all say 90)

Replyno of cones formed= (4/3 x 3.14x 15 x 15 x 15) / (1/3 x 3.14 x 2.5 x 2.5 x 8) = 90

[4/3 x 3.14 radius^3 is de volume of sphere while 1/3 x 3.14 x radius^2 x h is volume of cone]

i meant question 8 (b)
