MARKING BRAINLIST! PLEASE HELP!

Answer:

$\boxed {\boxed {\sf C. \ 4 \ inches}}$

Step-by-step explanation:

Circumference is the perimeter of a circle. It can be found using the formula:

$c= \pi d$

However, we are given the radius.

The radius measures from the center to the edge of the circle.
The diameter measures from edge to edge through the center.
So, the diameter is twice the radius, or d=2r

The formula can be rewritten as:

$c= \pi 2 r$

We know the circumference is 25.12 inches.

$25.12 \ in = \pi 2r$

Let's round pi to 3.14

$25.12 \ in = (3.14) 2r$

We want to solve for the radius, so we must isolate it.

Divide both sides by 3.14 because the inverse of multiplication is division.

$25.12 \ in / 3.14= (3.14 ) 2r / 3.14$

$8 \ in = 2r$

Divide both sides by 2.

$8 \ in / 2 = 2r/2$

$4 \ in = r$

The radius of the disc is <u>4 inches.</u>

This lesson discusses _____ related to the circle.

galina1969 [7]

Answer:

Theorems

Step-by-step explanation:

Theorems is the right answer.

A circle is a geometric figure where all points on the circle keep equal distances from a point called the centre.

A circle has so many important properties.

The important of these are called theorems related to circles.

Some of the theorems are

i)Central angle theorem

ii) Opposite angles are supplementary for a cyclic quadrilateral, etc

Hence theorems would be the appropriate word for filling up the answer

The general equation for depreciation is given by y = A(1 – r)t, where y = current value, A = original cost, r = rate of depreci

irina1246 [14]

Analyzing the given values and the given equation, we have the following:
A = $25,000
r = 0.11
t = 6

The equation has the form:
y = A (1-r)^t
Plugging in the given values into the equation,
y = $25,000 (1 - 0.11)^6
y = $25,000 (0.89)^6

Therefore, the answer is
A. y=25,000(.89)^6
