Using the approximation 3.14 for \pi what is the radius of a circle with circumference 44m

Mathematics
1 answer:
Feliz [49]3 years ago
8 0

Answer:

7 m

Step-by-step explanation:

Circumference of a circle uses the formula;

Circumference = 2 × pi × radius(r)

If the circumference = 44

then we use the formula above to calculate the value of the radius,

44 = 2 × pi × r...then divide both sides by (2 × pi(3.14))

Radius = 44 ÷ ( 3.14 × 2)

;Radius = 7.01

;Radius = 7m

A student is given this proof.
Alenkasestr [34]

From the steps below, it has been proved that  by transitive property of congruence, we can say that; ∠CON ≅ ∠BOM

<h3>How to prove congruent angles?</h3>

We are given;

∠AOM ≅ ∠DON

To prove that;

∠CON ≅ ∠BOM

Now, from the image attached, we can say that;

∠BOM ≅ ∠DON because of vertical angles theorem

Similarly, we can say that ∠AOM ≅ ∠BOM due to transitive property of congruence.

Also, we can say that from vertical angles theorem, ∠AOM ≅ ∠CON

Finally, since  ∠AOM ≅ ∠BOM, then by transitive property of congruence, we can say that;∠CON ≅ ∠BOM

Which of the following is an irrational number?
tamaranim1 [39]

Answer:

The correct option is;

0.100100010000...

Step-by-step explanation:

An irrational number in mathematics are the subset of real numbers that are not rational numbers such as √2, π, e. As such it is not possible to express an irrational number as a ratio of two integers, or expressed in the form of a simple fraction.

The decimal portion of the expression of an irrational number are non periodic and they do not terminate. Transcendental, which are non algebraic, numbers are all irrational numbers

In the question, the number 0.100100010000... has non terminating non recurring decimals and is therefore an irrational number.

1.) The deer population increases at a rate of 3% per year. There are 1253 deer this year. Write a function that models the deer
BabaBlast [244]
Exponential growth/decay rule with general function is:<span>y=y(0)<span>e<span>kt</span></span></span> with k is growth/decay constant rate.
(1) Deer population function y(0) = 1253 k
= 3% t
 = 6 (years)
  y(6) = 1253 . e^(0.03*6) ~ 1500 (deers)
: 1496 deers
 (2) Growth factor b is rate 9.5% = 0.095
