Answer 1

Answer:

Step-by-step explanation:

Tsa = CSA of all

Answer 2

Answer:

Step-by-step explanation:

TSA = csa of cone + csa of hemisphere

csa of cone = pi*r*l

height of cone = 15.5 - 3.5= 12 cm

l = root of r^2 + h^2

l = root of 3.5 x 3.5 + 12 x 12

= root of 12.25 + 144

= root of 156.25 = 12.5

therefore L = 12.5

csa of cone  = 22/7 x 3.5 x 12.5 = 137.5

now , csa of hemisphere = 2 x pi x r x r

csa = 2 x 22/7 x 3.5 x 3.5

therefore csa of hemisphere = 77

TSA of toy = 77 + 137.5

TSA = 214.4 cm^2
