Find the volume of curved surface area and total surface area with radius 5 and height 10cm
Answers
ANSWER ⇩
⇒Given,
•r= 5cm
•h= 10cm
•Volume of cone = 1/3πr²h
=1/3xπx5x5x10
=83.3cm³
•Slant height = √h²-r²
=√10²-5²
=√100-25
=√75
=5√3 (by prime factorization)
•C S A = πrl
=πx5x5√3
=25√3πcm²
•Base area =πr²
=πx5x5
=25πcm²
•T S A = curved surface area+base area
= 25√3π+25π
=(25√3+25)πcm²
