Circle o has a circumference of 28.3 cm. What is the length of the radius r?

andreyandreev [35.5K]

Circumference = 2Pi * r

28.3cm = 2pi * r ( Isolate r )
28.3cm / 2pi = r
R = 4.504

To verify work we can plug 4.504 back into the equations.

Circumference = 2pi*4.504 ~ 28.299 Which is true !

CAN ANYONE PLS HELP ME IN THIS PLS I WILL MARK U AS BRAINLIEST :) and pls show work

sergejj [24]

Answer:

(5.9 , 1)

Step-by-step explanation:

(1 , 0) (1 , 2) length = 2

Third vertex ( x , y)

(x - 1)² + (y - 0)² = 5²

(x - 1)² + (y - 2)² = 5² isosceles triangle

(y - 2)² - y² = 0

-4y + 4 = 0

y = 1

(x - 1)² + (1 - 0)² = 5²

(x - 1)² = 24

x - 1 = ± 2√6

x = 1 + 2√6 or x = 1 - 2√6

X in the 1st quadrant x = 1+2√6 = 5.9

Write as a product: ac^2–ad+c^3–cd–bc^2+bd

erastovalidia [21]

Answer:

$(a+c-b)(c^{2}-d)$

Step-by-step explanation:

The given equation is:

$ac^{2}-ad+c^{3}-cd-bc^{2}+bd$

We have to simplify it and convert to the product form, therefore taking the common terms from the given expression, we get

$a(c^{2}-d)+c(c^{2}-d)-b(c^{2}-d)$

Now, taking $(c^{2}-d)$ common from all the terms, we get

$(a+c-b)(c^{2}-d)$

which is the required product form of the given expression.

Josie is making pizza dough. Complete the double number line by filling in the missing values

Softa [21]

Answer:

$n = \frac{4}{3}c$

$c:0\ \ \ \frac{3}{4}\ \ \ \frac{3}{2}\ \ \ \frac{9}{4}\ \ \ 3\ \ \ 3\frac{3}{4}\\n:0\ \ \ \ 1\ \ \ 2\ \ \ 3\ \ \ \ 4\ \ \ \ 5$

Step-by-step explanation:

Given

See attachment for complete question

Required

Complete the double number line

The given double number lines represent a linear function between cups of flour (c) and number of batched (n)

Pick any two pairs:

$(c_1,n_1) = (\frac{3}{4},1)$

$(c_2,n_2) = (3\frac{3}{4},5)$

First, calculate the rate of change (i.e. slope, m):

$m = \frac{n_2 - n_1}{c_2 - c_1}$

$m = \frac{5-1}{3\frac{3}{4} - \frac{3}{4}}$

$m = \frac{4}{3}$

So: the equation is:

$n = m(c - c_1) + n_1$

This gives:

$n = \frac{4}{3}(c - \frac{3}{4}) + 1$

$n = \frac{4}{3}c - 1 + 1$

$n = \frac{4}{3}c$

So, the above represents the relationship between n and c.

To complete the table

When $n = 2$

Substitute $n = 2$ in: $n = \frac{4}{3}c$

$2 = \frac{4}{3}c$

Make c the subject

$c = \frac{3*2}{4}$

$c = \frac{3}{2}$

When $n = 3$

Substitute $n = 3$ in: $n = \frac{4}{3}c$

$3 = \frac{4}{3} * c$

Make c the subject

$c = \frac{3*3}{4}$

$c = \frac{9}{4}$

When $c=3$

Substitute $c=3$ in: $n = \frac{4}{3}c$

$n = \frac{4}{3} * 3$

$n = 4$

So, the complete table is:

$c:0\ \ \ \frac{3}{4}\ \ \ \frac{3}{2}\ \ \ \frac{9}{4}\ \ \ 3\ \ \ 3\frac{3}{4}\\n:0\ \ \ \ 1\ \ \ 2\ \ \ 3\ \ \ \ 4\ \ \ \ 5$
