Respuesta :

surface area of a cylinder = 2pi*r^2 + 2pi*rh

2. area = 2pi*2^2 + 2pi*2*15
= 68*pi
= 213.63 cm^2

3. area = 2pi*5^2 + 2pi*5*17
= 220*pi
= 691.15 ft^2

4. area = 2pi*8^2 + 2pi*8*22
= 480*pi
= 1507.96 mm^2

A = 2πrh + 2πr^2


2. A=2π*2*15 + 2π*2*2
= 213.6cm^2


3. A=2π*5*17 + 2π*5*5
= 691.2ft^2


4. A=2π*8*22 + 2π*8*8
= 1508.0mm^2

good job
