Answer 1

Answer:

Step-by-step explanation:

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.
