Question

plzz help me to find the answer​

Answer 1

Answer:

Hey mate here ia ur ans

Step-by-step explanation:

Given that, 

Radius (r) of cylindrical part = Radius (r) of hemispherical part = 3.5 cm 

Height of cylindrical part (h) = 10 cm 

Surface area of article = CSA of cylindrical part + 2 x CSA of hemispherical part 

= 2 π r h + 2 x 2 π r2 

= 2 π x 3.5 x 10 + 2 x 2 π x 3.5 x 3.5 

= 70 π + 49π 

= 119 π 

= 17 x 22 = 374 cm2 

Pls mark me as brainliest

Answer 2

Answer:

hey mate here is your answer....mark me as the brainiest

Step-by-step explanation:

height of cylinder is given 10 cm.

base of radius given 3.5cm.

here the total surface area is curved area of cylinder +surface area of two hemispheres

total surface area=2πrh+2(2πr^2)

=2πrh +4πr^2 or 2πr(h + 2r)

=2*22/7*3.5(10+2*3.5)

=22*17=374cm3..........
