Question

6. The total surface area of a right cone is 1,760 cmand the radius of its base is 14 cm. Find the
following for the cone.
(a) height
​

Answer 1

Answer:

h=21.9cm

Step-by-step explanation:

TSA of right cone= πr(r+l)=1760cm²

 22/7 ×14(14+l)=1760

22×2(14+l)=1760

44(14+l)=1760

14+l=1760/44

l=40-14

l=26cm

h=√l²-r²

h=√(26)²-(14)²

h=√676-196

h=√480

h=21.9cm

                              =
