Question

curved surfes area and circumference of the base of a solid right circular are 22oom square and 110m respectively find its height and radious​

Answer 1

Circumference= 2πr = 110m

=> r= 110x7/(2x22)

=> r= 17.5 m

CSA= 2πrh= 2200

=> h= 2200x7/(2x22x17.5)

=> h =7700/35 = 220m

therefore, r= 17.5m and h= 220m

Answer 2

Answer:

circumference of base =2*pi*r

                                 110=44*r/7

                                     r=17.5 cm

C.S.A of cone                =pi*r*l

                      2200       =22*17.5*l/7

                                    l =40 cm

                             l^2-r^2 =h^2

                             40^2-17.5^2=h^2

                           1600-306.25=h^2

                             h^2=1293.75

                             h=35.96 cm
