Question

TSA area of cylinder of height 5.5cm is 198cm2
​

Answer 1

Tsa =2πr(r+h)

198cm = 2×22/7 r (r + 5.5cm)

= 198 x 7/44 = r(r + 5.5cm)

= 31.5 = r^2 +5.5r

= 0 = r^2 +5.5r -31.5

r = 3.5

Answer 2

Answer:

i have got the answer

Step-by-step explanation:π

TSA=198CM2

π=3.14

H=5.5

TSA=πr(r+h)

PUTTING THE VALUES

198=3.14×r(r+5.5)

BY CUTTING WE GET

r^2=3.14-1089

r^2=1085.86

r=542.92
