A toy is in the f

As per the question:

The radius of the conical part = 3.5 cm

And,

Radius of the hemispherical part = 3.5 cm

Height of hemispherical part = Radius (r)

= 3.5 cm

= cm

Height of conical part (h) = 15.5 - 3.5 = 12 cm

for cone we know that,
r² + h² = l²
where r is the radius of base, l is the slant height and h is the height of cone.

Slant height of the conical part




=

=

Total surface area of toy = CSA of conical part + CSA of hemispherical part

= πrl + 2πr²

= 137.5 + 77

= 214.5 cm²
