Question

Find the percentage increase or decrease in the curved surface area of a cone if its

I. Slant height is halved. II. Radius is doubled​

Answer 1

Answer:

no change in percentage

Step-by-step explanation:

curved surface area of cone formula π*r*s

if slant height is halved then s will become s/2

if radius is doubled r will become 2r

hence,

π*r*s = 100%

π*2r*s/2 is  100 %

hence no change in percentage
