Answer:

257.5 feet

Step-by-step explanation:

A dome is circular in shape, therefore Circumference of the dome is the circumference of a circle which is calculated by

= 2 pi r

Given

Diameter = 82 feet

Radius r = diameter/2 = 82/2

= 41

Pi = 3.14

Therefore

Circumference = 2 x 3.14 x 41

= 257.48

= 257.5 feet

a tight roll of paper, as delivered to the printer, is 60cm in diameter, and the paper is wound on to a wooden cylinder 8cm in d
Alekssandra [29.7K]

The area of the paper is the amount of space it occupies.

The length of papers around the edge is 1607680 cm

The given parameters are:

\mathbf{d_1 = 60cm}

\mathbf{d_2 = 60cm + 8cm = 68cm}

The area of the circle head is:

\mathbf{Area = \pi \frac{d^2}{4}}

So, we have:

\mathbf{Area = \pi \frac{d_2^2 - d_1^2}{4}}

Substitute known values

\mathbf{Area = \pi \frac{68^2 - 60^2}{4}}

\mathbf{Area = \pi \frac{1024}{4}}

\mathbf{Area = 256\pi}

The length of the paper is then calculated as:

\mathbf{Length = \frac{Area}{0.0005}}

This gives

\mathbf{Length = \frac{256\pi}{0.0005}}

\mathbf{Length = \frac{256 \times 3.14}{0.0005}}

\mathbf{Length = 1607680}

Hence, the length of papers around the edge is 1607680 cm

Use the information given to enter an equation in standard form.
Greeley [361]

Answer:

y = -2x + 25

Step-by-step explanation:

A standard equation can be in slope-intercept form: y = mx + b

m is the slope, b is the y-intercept.

Plug in the given slope.

y = -2x + b

To find b, plug in the given point (9, 7).

7 = -2(9) + b

Multiply.

7 = -18 + b

Add 18 to both sides to find b.

25 = b

Plug this into your standard equation.

y = -2x + 25

Check by plugging in the given point again.

7 = -2(9) + 25

7 = -18 + 25

7 = 7

Your answer is correct!

Hope this helps!
