</span><span>the two hemispheres are equals
</span><span>
if </span><span>Tran computes the amount of paint needed to cover the sphere
</span><span>therefore
</span>Tran computes the amount of paint needed to cover <span>both hemispheres.
</span>
the answer is
Tran found the minimum amount of paint needed to cover both hemispheres.
[surface area of sphere]=4*pi*r²
[surface area of each hemisphere]=2*pi*r²
circumference=18.84 cm------> 2*pi*r------> r=18.84/(2*pi)------> 3cm
[surface area of each hemisphere]=2*pi*3²---------> 56.52 cm²
surface area of sphere=2*56.52=113.04 cm²
