Answer:

d = 2r => r = d/2 = 8ft/2 = 4ft

A = π·r²

= π·(4ft)²

= 16π ft²

= 16×3.14 ft²

= 50.24 ft²

Answer:

16π

Step-by-step explanation:

Area = πr²

r - radius

r = d/2 = 8/2 =4

Area = 4²π = 16π

Vikentia [17]

Answer:

x = 7

Explaination:

ABC = 40°

and BD bisects the angle so ABD = 20°

so 3x-1=20

solving for x gets us

What is the volume of a sphere with a surface area of ​ 16π ​ft²?
zheka24 [161]
Sphere Surface Area     =    <span> 4 • <span>π <span>• r²
For it to equal 16 PI, then radius must equal 2
4*PI*2*2 = 16 PI

</span></span></span>
Sphere Volume   = <span>  4/3 • <span>π <span>• r³
</span></span></span>
Sphere Volume   = <span>  4/3 • <span>π <span>• 2^3
</span></span></span>
Sphere Volume   = <span> 4/3 *PI * 8
</span>
Sphere Volume   = <span> 32 / 3 PI

</span>
Sphere Volume   = <span> 10.666 PI cubic feet AND I think that is answer B
which SHOULD read 10 (2/3) PI ft^3
</span>

Graph the equation on the coordinate plane.y=2x-1
Yakvenalex [24]

This equation is written in slope intercept form

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

In this case:

slope (m) is 2

y-intercept (b) is (0, - 1)

To plot this on a coordinate plane plot the y-intercept (0, -1).

To graph the rest of the line you can use what you know about the slope. Rise up two units and over to the right one unit from the y-intercept. You should arrive at the point (1, 1)

Then, again from the y-intercept, go down two units and to the left one unit. You should arrive at the point (-1, -3)

Now draw a straight line through the y-intercept and the other two points you just found

The image of the graph is shown below

Hope this helped!

A factory makes 1200 shirts every 6 hours.the factory makes shirts for 9 hours a workday. what is the fewest number of workdays
Dominik [7]
1. Divide the target number of shirts, 12,600 by the company's rate of making the shirts. That is,
                                 number of hours = 12,600 shirts/ (1200 shirts/6 hours)
                                                               = 63 hours
2. Determine the number of workdays for them to complete the shirts by dividing 63 hours by 9 hours/workday. This will give us an answer of 7 workdays.
