Answer:

50.24 cm

Step-by-step explanation:

Radius and Diameter:

r = d/2

d = 2r

Area of a circle:

A = πr2 = πd2/4

Circumference of a circle:

C = 2πr = πd

Circle Calculations:

Using the formulas above and additional formulas you can calculate properties of a given circle for any given variable.

Calculate A, C and d | Given r

Given the radius of a circle calculate the area, circumference and diameter. Putting A, C and d in terms of r the equations are:

A=πr2

C=2πr

d=2r

Calculate r, C and d | Given A

Given the area of a circle calculate the radius, circumference and diameter. Putting r, C and d in terms of A the equations are:

r=Aπ−−√

C=2πr=2πAπ−−√

d=2r=2Aπ−−√

Calculate A, r and d | Given C

Given the circumference of a circle calculate the radius, area and diameter. Putting A, r and d in terms of C the equations are:

r=C2π

A=πr2=π(C2π)2=πC24π2=C24π

d=2r=2C2π=Cπ

Calculate A, C and r | Given d

Given the diameter of a circle calculate the radius, area and circumference. Putting A, C and r in terms of d the equations are:

r=d2

A=πr2=π(d2)2=πd24

C=2πr=2πd2=πd

The phone company A Fee and Fee has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount o
IgorLugansk [536]

Answer:

y=0.2x+29

Step-by-step explanation:

Given that:

y is the total monthly of the A Fee and Fee plan.

x is the number of monthly minutes used.

  • If a customer uses 290 minutes, the monthly cost will be $87, we have the pair (290, 87)
  • If the customer uses 980 minutes, the monthly cost will be $225, this is the coordinate pair (980, 225).

We want to obtain an equation in the form: y=mx+b

First, let us determine the slope, m

Given points (290, 87) and (980, 225):

<u>Slope</u>

m=\dfrac{225-87}{980-290} =\dfrac{138}{690}=0.2

Next, we determine the y-intercept, b.

Substituting the pair (290, 87) and m=0.2 in y=mx+b, we obtain

87=0.2(290)+b

b=87-0.2(290)=29

Therefore, our equation in the form y=mx+b is:

y=0.2x+29

Please help and please show work<br>will give brainlyist
Komok [63]

If I am understanding this right, since the <em>c </em>is a variable, you'd have to solve the equation and have the variable in the and result.

the sqrt525^7 = 3359983566.19

So you'd have to simplify this and add the <em>c</em> to the end of it. Unless your work is fractions.

(I take Algebra II I should be more confident on this topic, this is just what makes the most sense)

Find the area of the shape shown<br> below.
steposvetlana [31]

Answer:

The area of the figure is 28 units².

Step-by-step explanation:

Find the area of the full rectangle, ignoring the triangle.

a = lw \\ a = 4 \times 8 = 32

Then, find the area of the triangle:

a =  \frac{bh}{2}  \\ a =  \frac{2 \times 4}{2}  \\ a = 4

Finally, subtract:

32 - 4 = 28
