Answer:

84.861

Step-by-step explanation:

In the given figure, 1/4 part of Circle is missing

so, we have to find the area of 3/4 part of circle

Area of circle = πr²

Given, r = 6

Now, Area of 3/4 part of circle = (3/4)×πr²

= (3/4) × 3.143 × 6²

= 84.861

The base of the pyramid is a square. what is the volume of the pyramid. enter your answer in the box.

Ugo [173]

Answer:

The volume of the pyramid is $672\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the pyramid of the figure is equal to

$V=\frac{1}{3}b^{2}h$

we have

$b=12\ cm$

$h=14\ cm$ ----> the height must be perpendicular to the base

substitute

$V=\frac{1}{3}(12^{2})(14)=672\ cm^{3}$

6x + 11 = 21<br> Help I’m on a quiz and this question is so confusing

Westkost [7]

Answer:

Step by Step Solution

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

6*x+11-(21)=0

Step by step solution :

STEP

Pulling out like terms

1.1 Pull out like factors :

6x - 10 = 2 • (3x - 5)

Equation at the end of step

STEP

Equations which are never true:

2.1 Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2 Solve : 3x-5 = 0

Add 5 to both sides of the equation :

3x = 5

Divide both sides of the equation by 3:

x = 5/3 = 1.667

One solution was found :

x = 5/3 = 1.667

20 POINTS AND BRAINLIEST!! Write an exponential function in the form y=ab^x

Rudik [331]

Answer:

$y=13(4)^x$

Step-by-step explanation:

We have the exponential function of the form:

$y=ab^x$

And it goes through the points (0, 13) and (3, 832).

Hence, when we substitute in 0 for x, we should get 13 for y. Therefore:

$13=ab^0$

Since anything to the zeroth power is 1, this yields:

$a=13$

So, we determined that the value of a is 13.

So, our function is now:

$y=13b^x$

We will need to determine b. We know that y equals 832 when x is 3. Hence:

$832=13(b)^3$

Divide both sides by 13:

$b^3=64$

Take the cube root of both sides:

$b=4$

Hence, our b value is 4.

Therefore, our entire equation is:

$y=13(4)^x$
