Question

A circular metallic plate of radius 8 CM and thickness 6mm is melted and molded into a proof radius 16 CM and thickness 4 Mm find the angle of thesector

Answer 1

Answer:

the volume of the circular metallic plate. It can be found by multiplying the area of the the

circle with it's thickness as:

Now, radius = 8 cm

thickness = 6 mm = 6/10cm

Therefore, volume,

Now, the volume of the remolded pie will be the product of the area of the pie and the thickness of the pie.

Now the area of the pie is

radius = 16cm

thickness = 4 mm = (4/10)m

NOW, the volume of the circular metallic plate = the volume of the remolded pie

so,

HENCE, the angle of the sector is 135°
