Question

find the;
i) curved surface area
ii) total surface area and
iii) volume of a right circular cylinder whose hight is 15 cm and the radius of the base in 12 cm. ​

Answer 1

H= 15cm , R = 12cm

a) CSA = 2πrh = 2×22/7×15×12 = 41.14 cm^2

b) TSA = 2πr(r+h) = 2×22/7×12(15+12) = 22×24×27/7

= 1110.85cm^2

c) Volume = πr^2h = 22/7×12×12×15 = 6788.57cm^3

hope it helps you

Answer 2

Answer:

write like this

Step-by-step explanation:

Radius of cylinder (r)=7cm

Height of cylinder (h)=15cm

Curved Surface Area =2πrh

=2×(22/7)×7×15

=660cm

2

Total Surface Area =2πr(h+r)

=2×(22/7)×7(15+7)

=2×22×22

=968cm
