tsa - 2*pi*r²+2*pi*r*(h-2r)+2*pi*r²
r=7
h=104
tsa=2*pi(7²+90*7+7²)=2*22*104=4576 cm²=45.76dm²
so total cost = 45.76*10=457.60 rupees
r=7
h=104
tsa=2*pi(7²+90*7+7²)=2*22*104=4576 cm²=45.76dm²
so total cost = 45.76*10=457.60 rupees

4th one
If u know then please solve it also
i m sending u the answer asamessage
what r u saying I am not understanding
tsa =pi*r^2+2*pi*r*h+pi*r*l
thanks
r=5, h=12, l=root(5^2+12^2)=13
so ans is 660cm2
Thanku ur maths is good
awww.. thanks.. :)
