please answer me

i will make as the brillanst

you tell the correct answer

please​

Answer 1

Explanation:

Surface area to colour=surface area of hemisphere+curved surface area of cone

Surface area of hemisphere

Diameter of hemiy=3.5cm

so, radius=3.5/2

surface area of hemisphere=2πr^2

=2×22/7×(3.5/2)^2

2×22/7×3.5/2×3.5/2

11×0.5×3.5

19.25cm^2

Curved surface area of cone=πrl

radius=3.5/2=1.75cm

hight of cone=hight of top-radius of hemisphere

= 3.25cm

sorry yar I got still hear only
