A metallic sphere of radius 10 .5 cm is melted and then recast into small cones each of radius 3.5 cm and height 3 cm the number of such cone is

Step-by-step explanation:

Number of cones = Volume of Sphere/Volume of one cone

Volume of sphere = (4/3)πr³

Volume of cone= (1/3)πr²h

Number of cones = 1543.5π / 12.25π

       = 126 cones

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
