Question

plz answer my ques......​

Answer 1

Dimensions:-

→h=9m(cylinder)

→r=28 m

→L=35m

TSA of Cylinder=2πr(r+h)

TSA of Cone=πr(r+l)

TSA of Cylinder

→2×22/7×28(28+9)

→176(37)

→6,512m²

TSA of Cone

→22/7×28(28+35)

→88(63)

→5,544m²

Total surface area(TSA of Cylinder+TSA of Cone)

Area= l×b

→6,512m²+5,544m²=l×b

→12,056=l×8

$\frac{12056}{8} = l = 1507$

Hope it Helps✌
