The radius of the cone is 5 in and y = 13 in. What is the volume of the cone in terms of π?

olga nikolaevna [1]

Answer:

The volume of the cone is;

100 π inches^3

Step-by-step explanation:

To calculate the volume, we need the height

We can get the height from the slant height and the radius

Mathematically, we use Pythagoras’ theorem for this as the slant height, the radius and the height forms a right-angled triangle

The right-angled triangle has the slant height as its hypotenuse

By the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides

Let the height be h

Thus;

12^2 = 5^2 + h^2

169= 25 + h^2

h^2 = 169-25

h^2 = 144

h = √1144 inches = 12 inches

The volume of the cone is;

1/3 * π * r^2 * h

= 1/3 * π * 5^2 * 12

= 100 π inches^3

Which of the following equations have infinitely many solutions? Choose all answers that apply: Choose all answers that apply: (

TiliK225 [7]

Answer:

All options are correct.

Step-by-step explanation:

In option (A), the given equation is

$x-37=x-37$

Add 37 on both sides.

$x-37+37=x-37+37$

$x=x$

Subtract x from both sides.

$x-x=x-x$

$0=0$

LHS=RHS for all values of x. It means equation x-37=x-37 has infinite many solutions.

Similarly.

In option (B), the given equation is

$73x-37=73x-37$

$73x=73x$

$0=0$

LHS=RHS for all values of x. It means equation 73x-37=73x-37 has infinite many solutions.

In option (C), the given equation is

$37x-37=37x-37$

$37x=37x$

$0=0$

LHS=RHS for all values of x. It means equation 37x-37=37x-37 has infinite many solutions.

In option (D), the given equation is

$74x-37=74x-37$

$74x=74x$

$0=0$

LHS=RHS for all values of x. It means equation 74x-37=74x-37 has infinite many solutions.

Therefore, all options are correct.

-1/3+(-3/5)=

Illusion [34]

$\frac{-1}{3} + \frac{-3}{5}$
You need to use the equation for adding fractions, which is $\frac{a}{b} + \frac{c}{d} =(ad+bc)/bd$

In this case, a=-1, b=3, c=-3, d=5.

$
 \frac{(-1*5)+(3*-3)}{(3*5)}$

simplify

answer: $\frac{-14}{15}$

PLEASE HELP ME!!! I NEED HELP WITH GEOMETRY QUESTION ASAP!! DESPRATLY

BartSMP [9]

Answer:

The answer to your question is: y = -3x + 14

Step-by-step explanation:

Data

A (4, 2)

y = x/3 - 1

Perpendicular

original slope = 1/3

perpendicular slope = -3

Equation (y - y1) = m(x - x1)

(y - 2) = -3(x - 4)

y - 2 = -3x + 12

y = -3x + 12 + 2

y = -3x + 14
