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

If a 36-foot tree casts a 28-foot shadow at the same time near by building casts a 70-foot shadow, how tall is the building?
Arada [10]
Actual length / shadow ratio is equal
Let the height of the building be x, then
36/28 = x/70
x = (36 x 70)/28 = 2,520/28 = 90.

Therefore, the height of the building is 90 feet.
