Given: r=5 ft, h=25ft

Formula: 2πr(r+h)

= 2×3.14×5ft(5ft+25ft)

=31.4ft(30ft)

=942ft²

Formula: 2πrh+2πr²

=2×3.14×5ft×25ft + 2×3.14×5²

=785ft² + 157ft²

=942ft²

Formula: 2πr(r+h)

= 2×3.14×5ft(5ft+25ft)

=31.4ft(30ft)

=942ft²

Formula: 2πrh+2πr²

=2×3.14×5ft×25ft + 2×3.14×5²

=785ft² + 157ft²

=942ft²
