Question 388008
formulas that apply:
area of a circle = pi*radius^2
circumference of circle = 2 *pi *radius
area of  cylinder = 2 *pi *radius *h
area of sphere or 2 hemispheres= 4*pi*radius^2
volume of a sphere = 4/3 *pi*radius^3
volume of clinder =pi*radius^2*h
pi = 3.14

surface area of  first tablet = surface area of cylinder + surface are of 2 hemispheres on  each end
surface area of cylinder = (2 *pi *radius *h) =2*pi*.3*2.4=4.52
surface area of 2 hemispheres =4*pi*radius^2 = 4*pi*.3^2=1.13

surface area of first tablet = 4.52+1.13 = 5.65 cm^2

a)as stated, area of second tablet =area of first tablet =2 *pi *radius *.6=5.65

radius = 5.65/(2*pi*.6) = 1.5 cm

b) volume of first tablet = (4/3 *pi*radius^3)+(2 *pi *radius^2 *h)
=(4/3 *pi*.3^3)+(2*pi*.3^2*2.4)=.113+1.36 =1.47 cm^3

volume of second tablet = pi*radius^2*h=pi*1.5^2*.6 =4.24 cm^3


ans: a) The radius of the second tablet is 1.5 cm
       b) The volume of the first tablet is 1.47 cm^3
            The volume of the second tablet is 4.24 cm^3
