Answer:

The area of the piece of paper is 466 cm²

Step-by-step explanation:

First you would want to find the area of the rectangle

39x20=780 cm²

Both semi-circles are the same, so you can just find the area of the whole circle

The diameter is 20 cm so you would use 10 as the radius

A=πr²

A=3.14x10²

A=3.14x100

A=314

Then you have to subtract the area of the circle from the area of the rectangle.

780-314=466

The area of the piece of paper is 466 cm²

[tex]6\pi = \boxed{18.9ft}[/tex]

9514 1404 393

Answer:

  18 6/7 ft

Step-by-step explanation:

The circumference is given by the formula ...

  C = 2πr

The circumference of the larger circle is then ...

  C' = 2π(r+3) = 2πr +6π

The difference in circumference is ...

  C' -C = (2πr +6π) -(2πr) = 6π

For the given value of π, the difference in circumference is ...

  (22/7)(6 ft) = 132/7 ft = 18 6/7 ft

The circumference of the outer circle is greater by 18 6/7 ft.

Answer:

60 miles

Step-by-step explanation:

There are two ways to solve this:

1. They tell you that you drive at 60 miles an hour, so , in an hour, you drive 60 miles.

2. Is the way you should use in the future:

Distance = speed * time

Substitute the speed and times.

Distance = 60 * 1

Thus, you drive 60 miles in one hour

The distance that should be traveled be 60 miles

As we know that

[tex]Speed = \frac{distance}{time}[/tex]

Here

speed be 60 miles per hour

And, the time should be one hour

So, the distance should be

[tex]= 60\ miles\ per hour \times one\ hour[/tex]

= 60 miles

Therefore the distance that should be traveled be 60 miles

Answer:

75 degrees

Step-by-step explanation:

All the interior angles of a triangle add up to 180 degrees. Knowing this, we can construct the following equation:

180=65+40+x

180=105+x

Subtract both sides by 105

180-105=105+x-105

75=x

Therefore, angle C has a measure of 75 degrees.

The answer is below

Step-by-step explanation:

A triangular pyramid is a pyramid with a triangular base. It is a polyhedron (3 dimensional shape) composed of four triangular faces, six straight edges, and four vertex corners.

The surface area of a triangular pyramid with congruent equilateral triangles = 4 * area of one triangle

Area of one triangle = (1/2) * base * height  = (1/2) * 15 in * 13 in = 97.5 in²

Surface area of pyramid = 4 * 97.5 in² = 390 in²

Answer:

a). -6x³ - 12x²    b). -12     c). 12

Step-by-step explanation:

a). (g x f)(x) can also equal f(g(x))

= f (2x +4)

= -3x² (2x+4)

= -6x³ - 12x²

b). f(g(-1))

g(-1) = 2(-1) + 4

= -2 + 4

= 2

f(2) = -3x²

= -3(2)²

= -12

c). g(h(3))

h(3) = 3x-1/2

= 3(3) - 1 / 2

= 4

g(4) = 2x + 4

= 2(4) + 4

= 12

it is gonna be c trust me I know for a fact

Given:

In triangle DEF, [tex]DE = EF[/tex] and [tex]m\angle 98^\circ[/tex].

To find:

The measure of angle EFD.

Solution:

In triangle DEF,

[tex]DE = EF[/tex]           (Given)

It means triangle DEF is an isosceles triangle.

[tex]m\angle EDF=m\angle EFD[/tex]           (Base angles of an isosceles triangle are equal)

Using angle sum property in triangle DEF, we get

[tex]m\angle DE F+m\angle EFD+m\angle EDF=180^\circ[/tex]

[tex]98^\circ +m\angle EFD+m\angle EFD=180^\circ[/tex]

[tex]2m\angle EFD=180^\circ-98^\circ[/tex]

[tex]2m\angle EFD=82^\circ[/tex]

Divide both sides by 2.

[tex]m\angle EFD=\dfrac{82^\circ}{2}[/tex]

[tex]m\angle EFD=41^\circ[/tex]

Therefore, the measure of angle EFD is 41 degrees.
