Volume of cylinder with the given height and radius or diameter

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

1) diameter = 4 inches

Radius = diameter/2 = 4/2 = 2 inches

Height = 10 inches

Volume = 3.14 × 2² × 10 = 125.6inches³

2) Radius = 20 cm

Height = 50 cm

Volume = 3.14 × 20² × 50 = 62800 cm³

3) diameter = 16 mm

Radius = diameter/2 = 16/2 = 8 mm

Height = 10 mm

Volume = 3.14 × 8² × 10 = 2009.6 mm³

4) Radius = 9 feet

Height = 9 feet

Volume = 3.14 × 9² × 9 = 2289.06 ft³

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
