Heya User,

Answer the Question :-

If radius of the base of a cone is 140 dm and its slant height is 9 m. Find the

(i) curved surface area

(ii) total surface area

Answer 1

Height =24cm

radius =14÷2=7cm

slant height=L=?

L2=R2+H2

L2=72 +242

L2=49+576

L2=625

L=25

VOLUME=1÷3×22÷7×7×24

VOLUME=1232CM

CURVED SURFACE AREA =22÷7×7×25

CURVED SURFACE AREA =550

TOTAL SURFACE AREA=22÷7×7×25+7

TOTAL SURFACE AREA =704CM
