Csa-pie r2 h=22/7*7*7*6=924cm2
Area of base =2pie r2
= 2*22/7*7*7
=308 cm2
TSA= Csa +2(area of base)
=924+2(308)
=1540cm2
Area of base =2pie r2
= 2*22/7*7*7
=308 cm2
TSA= Csa +2(area of base)
=924+2(308)
=1540cm2

Csa - 2pie rh = 2*22/7*7*6 =264cm2 area of base - pie r2=22/7*7*7=154cm2 tsa=2pie r(r+h)=2*22/7*7(7+6)=572cm2
aree sry
