What is the circumference of a circular disc with a diameter of 10 centimeters? (Round your answer to the nearest tenth.)

1 answer:

5 0

To determine what the circumference is simply take the value of the diameter and multiply it to the value of Pi or 3.141....

C = Pi • d
C = (3.14)(10 cm)
C = 31.41 cm or 31.4 cm, rounded to the nearest tenth.

A horse walks around a circular track while its trainer stands in the center. The trainer is 14 feet from the horse at all times

max2010maxim [7]

The horse traveled 439.6 feet after walking around the track 5 times

Solution:

Given that, horse walks around a circular track while its trainer stands in the center

The trainer is 14 feet from the horse at all times

Therefore, radius of circular track = 14 feet

The circumference of circle is the distance traveled by horse for 1 lap

The circumference of circle is given as:

$C = 2 \pi r$

Where, "r" is the radius and $\pi$ is a constant equal to 3.14

$C = 2 \times 3.14 \times 14\\\\C = 87.92$

Thus the distance traveled by horse for one time in circular track is 87.92 feet

About how far had the horse traveled after walking around the track 5 times?

Multiply the circumference by 5

$distance = 5 \times 87.92\\\\distance = 439.6$

Thus the horse traveled 439.6 feet after walking around the track 5 times

(Need 3 answers) An entomologist discovered a new insect species. The population of the insect species can be modeled by P(n) =

Strike441 [17]

Answer:

See below

Step-by-step explanation:

According to the model, the equation is:

P(n) = 3450*bⁿ

Based on the equation, the initial number of insects is 3450

If b = 1.75, daily growth rate is:

1.75 - 1 = 0.75 = 75%

If we get P(4) = 55200, find the value of b:

55200 = 3450*b⁴
b⁴ = 55200/3450
b⁴ = 16
b⁴ = 2⁴
b = 2
