ORAta Ramzan Mela, a stall keeper in one of the food stalls has a largewindrical vessel of base radius 15 cm filled up to a height of 32 cm withorange juice. The juice is filled in small cylindrical glasses(see in figure ofradius 3 cm up to a height of 8 cm, and sold for Rs 3 each. How much moneydoes the stall keeper receive by selling the juice completely?

Answer»

Total volume of orange juice = volume of cylindrical vessel=pi * r^2 * h= 22/7 * 15^2 * 32= 22*225*32/7 cm^3= 22628.57cm^3

volume of orange juice in 1 glass= 22/7 * 3^2 * 8cm= 22*9*8/7 cm^3= 226.29 cm^3

No. of glasses = total volume of orange juice/volume of juice in 1 glass= 22628.57 cm^3/226.29 cm^3= 100 glasses

Therefore, Money stall keeper receive by selling the juice= 100*3= Rs 300

A hemispherical vessel of radius 14 cm is fully filled with satfully filled with sand. This sand15 poured on a level ground. The heap of sand forms a cone shapis a cone shape of height7 cm. Calculate the area of ground occupied by the circular bad by the circular base of theheap of the sand.

Answer»

Given,Radius of hemisphere r1 = 14 cm

Height of cone h = 7 cm

Let radius of base of cone = r2

Volume of hemisphere Vh= 2/3*pi*(r1)^3= 2/3*pi*(14)^3

Volume of cone Vc= 1/3*pi*r2^2*h= 1/3*pi*r2^2*7

As per given conditionVc = Vh1/3*pi*r2^2*7 = 2/3*pi*(14)^3r2^2 = 2*2*14*14r2 = 2*14r2 = 28 cm

Therefore,Area of base of cone= pi*r2^2= 22/7*28*28= 22*4*28= 88*28= 2464 cm^2

le 3.2 The position of an objectmoving along x-axis is given by x a+bewhere a 8.5 m, b 2.5 m s2 and t ismeasured in seconds. What is its velocity att-O s and t 2.0 s. What is the averagevelocity between t # 2.0 s and t:40 s?amp

Answer»

X = a + bt^2v = 2bt

Velocity at t = 0 is 0Velocity at t = 2s is = 2*2.5*2 = 10 m/s

At t = 2sx = 8.5 + 2.5*2^2x = 18.5m

At t = 4s x = 8.5 + 2.5*4^2x = 48.5m

Average velocity = (48.5 - 18.5) / 2 = 15m/s
