Answer:area =3351.07 cm2
Vol. =23.7lit.
Step-by-step explanation:
Firstly we have to find the slant height of the frutum
.... Calcute it
Slant height =26cm
Now,area of. Metallic sheet =csa of frustum +area of Base of frustum
PieL(r1 +r2) +pie r2(25)
Calculate it...
3351.07cm2
Now for vol.,
1/3pieh(r2+r2+rr)
Put values and calculate it,
It come 23.7...lit.
Vol. =23.7lit.
