Question

A solid wooden toy is in the shape of a right circular cone mounted on a hemisphere. Of the radius of the hemisphere is 3.5cm

Answer 1

bro I think the question is incomplete but yet I am answering I hope this is a question which I am answering
radius of hemisphere=3.5cm
height of toy=15.5cm
height of cone=15.5-3.5=12cm
slant hight of cone =root (12)^2+(3.5)^2
☆root 144+12.25
☆root 156.25
=12.5cm
so according to question
total surface area of the toy will be = curved surface area of hemisphere + curved surface area of cone
☆2×22/7×(3.5)^2+22/7×3.5×12.5
☆77+137.5
=214.5cm^2
show the total surface area of the toy will be 214.5 CM square
who this will help you and please mark me as brainlist
