Diagram I shows another hollow cone whose sloping edge is of length cm. The radius of
the circular top is rem. The cone is cut along its sloping edge and laid flat to form the
sector OPO of a circle of radius rem as shown in Diagram II
Find an expression, in terms of r, for the length of the arc PQ.
It is given that I = 57.
(a) Calculate PÔQ
(b) Given also that 1 = 40, calculate the area of the sector OPQ, expressing your
answer as a multiple of n.

Read the following information and prepare a pie diagram.
Water is life. It is a universal solvent and an important resource. The annual usage of water differs
in various sectors of Maharashtra. The major occupation of Maharashtra being agriculture, the
maximum amount of available water is used for irrigation that is 86%. The distant following place
7% is contributed by domestic sector including drinking, washing, cooking etc. There is a close
competition of other sectors which is not faraway with 6% usage of water. One of the key factors
which plays an important role in the development of a nation is industrial sector. The consumption
of water by industrial sector is very negligible which 1% is. We know energy sector plays a vital role
in the development of a nation.
In this sector, the use of water is also nil. If we try to observe its place in the chart we do realize that
it holds 0% usage and is yet to open.iagram I shows another hollow cone whose sloping edge is of length cm. The radius of
