Answer:

Inputs:

Radius (r):

0.65

or

Diameter (d):

1.3

or

Area (A):

1.327

Unit of Lenght:

centimeter

Calculate Circumference

Result:

The circumference of a circle with diameter 1.3 is 4.084(*)

Formulas:

r = 0.65

d = 1.3

C = 4.08

C = 2·π·r C = π·d C = √4·π·A π = 3.1415

A = area of the circle

C = circumference or perimeter

r = radius, d = diameter

Step-by-step Solution:

Circumference of a cicle in terms of radius:

Circumference = 2·π·r = 2·3.14·0.65 = 4.09(*)

In terms of diameter:

Circumference = π·d = 3.14·1.3 = 4.08(*)

In terms of area:

Circumference C = √4·π·A = √4·π·1.33 = 4.09(*)

(*) 4.084 cm exactly or limited to de precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

A circumference of 4.084 centimeters is equal to:

4.084E-5 kilometers (km)

0.04084 meters (m)

40.84 millimeters (mm)

2.53768E-5 miles (mi)

0.0446632 yards (yd)

0.13399 feet (ft)

1.60787 inches (in)

Step-by-step explanation:

The formula for a circumference of a circle is

\pi \times d

where d is the diameter.

So the answer is

\pi \times 1.3

1.3\pi

If you asked to use 3.14 as a approximation for pi then we do

1. 3 \times 3.14 = 4.082

The equation V equals pi r squared h, where r represents radius and h represents height, is used to find the volume of a _______
baherus [9]

Answer:

Volume of a cylinder.

Step-by-step explanation:

The given equation is :

V=\pi r^2 h

Where

r is the radius

h is the height

This equation is used to find the volume of a cylinder.

For example, a cylinder having radius of 7 units and height of 10 units, its volume will be :

V=\dfrac{22}{7}\times 7^2\times 10\\\\V=1540\ \text{unit}^2

So, the given equation is used to find the volume of a cylinder.

grin007 [14]

Answer:

FV= 5,958.67 = 5,959

Step-by-step explanation:

Giving the following information:

Current population (Present Value)= 3,810

Growth rate (g)= 3.5% annual

Number of periods (n)= 13 years

<u>To calculate the future number of people (FV), we need to use the following formula:</u>

FV= PV*(1+i)^n

FV= 3,810*(1.035^13)

FV= 5,958.67 = 5,959
