Answer: Area of sector in term of π is 24 in.².

Step-by-step explanation:

Since we have given that

Radius of the sector of a circle = 12 inch

Central angle = 60°

As we know the formula for "Area of sector":

Area=\frac{\theta}{360^\circ}\pi r^2\\\\Area=\frac{60}{360}\times \pi\times 12\times 12\\\\Area=24\pi\ inch^2

Hence, Area of sector in term of π is 24 in.².

Answer:

The exact area of the sector in terms of ​π is 24\pi \thinspace inches^2

Step-by-step explanation:

Given the radius of circle 12-inch and the central angle measure of 60°.

We have to find the the exact area of the sector in terms of ​ π.

As the area of sector can be calculated by the formula

A=\frac{\theta}{360^{\circ}}\times\pi r^2

where \theta is the central angle in degree and r is the radius of circle.

Now, A=\frac{60}{360^{\circ}}\times\pi (12)^2

              =\frac{1}{6}\times\pi (12)^2

              =24\pi \thinspace inches^2

Hence, the exact area of the sector in terms of ​π is 24\pi \thinspace inches^2

TriangleABC is transformed to form  triangleA'B'C' .
ExtremeBDS [4]
A=(2,4); B=(3,9); C=(4,1)
A'=(4,-2); B'=(9,-3); C'=(1,-4)

All the points P=(x,y) change to P'=(y,-x), this corresponds to a rotation counterclockwise about the origin, then:

Answer: Triangle ABC is
First box: rotated counterclockwise
Second box: 90° about the origin

How do you find a volume of a cone?
Dennis_Churaev [7]

Answer:

  V = (1/3)πr²h

Step-by-step explanation:

The volume of a cone is 1/3 the volume of a cylinder with the same radius and height.

  Cylinder Volume = πr²h

  Cone Volume = (1/3)πr²h

where r is the radius (of the base), and h is the height perpendicular to the circular base.

_____

<em>Comment on area and volume in general</em>

You will note the presence of the factor πr² in these formulas. This is the area of the circular base of the object. That is, the volume is the product of the area of the base and the height. In general terms, ...

  V = Bh . . . . . for an object with congruent parallel "bases"

  V = (1/3)Bh . . . . . for a pointed object with base area B.

This is the case for any cylinder or prism, even if the parallel bases are not aligned with each other. (That is, it works for oblique prisms, too.)

Note that the cone, a pointed version of a cylinder, has 1/3 the volume. This is true also of any pointed objects in which the horizontal dimensions are proportional to the vertical dimensions*. (That is, this formula (1/3Bh), works for any right- or oblique pyramid-like object.)

__

* in this discussion, we have assumed the base is in a horizontal plane, and the height is measured vertically from that plane. Of course, any orientation is possible.
