Question

write the total surface area of a right circular solid cone having radius 10cm and slant height 25cm take π has 22/7

​

Answer 1

Answer:

tsa=

$2\pi \: r(r + l)$

2x22x10(10+25)/7=2200 cm^2

Answer 2

we know that. TSA OF right cylinder is

πr(l+r)

1. r=10cm

2.slant height = l = 25 cm

therefore ,

22/7*10(10+25)

22/7*10(35)

22/7*350

1100cm2
