Answer:

Step-by-step explanation:

Hello there, to answer this question, one must know the formula of area of a circle.

1. Use formula for area of circle to find area of base of cylinder

2. Multiple area of base with height of cylinder for volumne

Area = pi * r * r

Cylinder A:

Area: pi * 6 * 6 = 113.1 inches square

Volumne = Area * Height = 113.1 * 4 = 452.4 inches cube

Cylinder B:

Area: pi * 5 * 5 = 78.54 inches square

Volumne = Area * Height = 78.54 * 5 = 392.7 inches cube

Cylinder C:

Area: pi * 4 * 4 = 50.27 inches square

Volumne = Area * Height = 50.27 * 6 = 301.62 inches cube

The chairs in a school were arranged in 15 rows with 28 chairs in each row if these chairs were rearranged into rows of 20 how m

ludmilkaskok [199]

Answer: 21 rows

Step-by-step explanation:

First find out the number of chairs that are currently in the school.

= 15 rows * 28 chairs

= 420 chairs

If 420 chairs were to be arranged in rows of 20, the number of rows would therefore be:

= 420 / 20 per row

= 21 rows

Troyanec [42]

Answer:

t = 6.77 s

Step-by-step explanation:

Given that,

A drop of paint falls from a rafter that is 225 feet above the ground.

We need to find the time when the paint hit the ground. Let the time be t.

Using the second equation of kinematics i.e.

$s=ut+\dfrac{1}{2}at^2$

Where

u = 0 (initial velocity is 0 as it was at rest)

a = g

So,

$225=\dfrac{1}{2}\times 9.8t^2\\\\t=\sqrt{\dfrac{2\times 225}{9.8}} \\\\t=6.77\ s$

So, it will hit the ground at 6.77 s.
