Radha, an aspiring landscape designer, is tasked with creating a visually
captivating pool design that incorporates a unique arrangement of fountains.
The challenge entails arranging the fountains in such a way that when water is
thrown upwards, it forms the shape of a parabola. The graph of one such
parabola is given below.
The height of each fountain rod above water level is 10 cm. The equation of the
downward-facing parabola representing the water fountain is given by

Find the zeroes of the polynomial p(x) from the graph.
(ii)
Find the value of x at which water attains maximum height.
(iii)(A)
If h is the maximum height attained by the water stream from the water level of
the pool, then find the value of h.

38. Rinku was very happy to receive a fancy jumbo pencil from his best friend Rohan
on his birthday. Pencil is a basic writing tool, when sharpened its shape is a
combination of cylinder & cone as given in the picture.
Cylindrical pencil with conical head is a common shape worldwide since ages.
Commonly pencils are made up of wood & plastic but we should promote pencils
made up of eco-friendly material (many options available in the market these
days) to save environment.
The dimensions of Rinku’s pencil are given as follows:
Length of cylindrical portion is 21cm. Diameter of the base is 1 cm and height of
the conical portion is 1.2 cm
Based on the above information, answer the following questions:
(i)
Find the slant height of the sharpened part.
(ii)
Find curved surface area of sharpened part (in terms of 𝜋).
(iii)(A)
Find the total surface area of the pencil (in terms of 𝜋).
The pencil’s total height decreases by 8.2 cm after sharpening it many times,
what is the volume of the cylindrical part of the shortened pencil (in terms of 𝜋)?
