Answer:  The correct option is

(C) 2700\pi~\textup{units}^3.

Step-by-step explanation:  We are given to find the volume of the cone in the figure.

We know that the VOLUME of a cone with radius r units and height h units is given by

V=\dfrac{1}{3}\pi r^2h.

From the figure, we note that

radius, r = 10 units and  height, h = 81 units.

Therefore, the VOLUME of the cone will be

V\\\\\\=\dfrac{1}{3}\pi r^2h\\\\\\=\dfrac{1}{3}\pi\times 10^2\times 81\\\\\\=27\times 100\pi\\\\=2700\pi~\textup{units}^3.

Thus, the volume of the cone is 2700\pi~\textup{units}^3.

Option (C) is CORRECT.

The opposite angles of a parallelogram are equal.
Therefore
m∠A = m∠C, so that
5y - 3 = 3y + 27
Subtract 3y from each side.
5y - 3y - 3 = 3y - 3y + 27
2y - 3 = 27
Add 3 to each side.
2y - 3 + 3 = 27 + 3
2y = 30
y = 30/2 = 15

Therefore
m∠A = 5*15 - 3 = 72°
m∠C = 72°

Let x = m∠B
Then x = , m∠B = m∠C
Because the sum of the angles in the parallelogram is 360°, therefore
x + x + 72 + 72 = 360
2x = 360-144 = 216
x = 216/2 = 108

Answer:
m∠A = 72°
m∠B = 108°

Some please help me I’ll give you brainlist answer
Montano1993 [528]

Answer:

Step-by-step explanation:

The area of the square is 3 units by 3 units. because the area of a square is side length squared.

side length = 3

side length^2 = 3 * 3 = 9

The area of a circle is much harder to reason out. You could start with the area of a square and use the diameter is 3 units. But the corners are rounded and you don't know off hand what the area of one of them is, let alone all 4. You are given a formula for circles area, but you have no real idea what the formula actually means. Does it take the corner area into account? At the beginning levels, we don't know.

What are the solutions to the equation 0 = x2 - X-6? Select two options
Ganezh [65]

Step-by-step explanation:

x2 - x - 6 = 0

x2 - 3x + 2x - 6 = 0

x(x - 3) + 2(x - 3) = 0

x - 3 = 0. x + 2 = 0

x = 3 x = - 2

Option no 2 and 5 are the correct answer
