Aspen Oconnor · Answer 1

V = 1570.796327 cm^3

Step-by-step explanation:

V = pi * r^2h

diameter = 2 * radius

10 = 2r

r = 5

substitute in what we know

V = pi * (5^2) * 20

V = pi * 25 * 20

V = pi * 500

V = 1570.796327 cm^3

Laylah Hansen · Answer 2

Step-by-step explanation:

Surface Area of circle on top of cylinder:

= πr²

= π (d:2) ²

= π (10:2) ²

= π (5) ²

= 25π

Volume of Cylinder:

= 25π * h

= 25π * 20

= 500π

= 1570.8 cm³ (to 1 decimal place)
