Answer:
56844.9 units squared
Step-by-step explanation:
The surface area of a cone is denoted by: , where r is the radius and l is the slant height. The slant height is basically the length from a point on the base circle to the top vertex of the cone.
Here, since our diameter is 50 and diameter is twice the radius, then our radius is r = 50/2 = 25.
To find the slant height, we have to use the Pythagorean Theorem:
, where h is the height
Now, plug these values of r and l into the first equation above:
≈ 56844.9 units squared
Answer:
23 dollars
Step-by-step explanation:
so to figure out how much more you grab 20 and multiply by .15 as percent and you will get 3 dollars more so 23
Hi! Your answer is y = x + 4
Please see an explanation for a better and clear understanding to your problem!
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Here are the reasons why it's A choice which is y = x + 4.
- The graph passes through y-axis at (0,4) which makes it obvious that the graph has y-intercept/b-value equal 4.
- The graph has slope of 1. We can tell by rise over run (A glance can tell that the graph has slope of 1.)
- Other choices have y-intercept at (0,0) also known as "origin point". The graph shown doesn't pass an origin point but passes through (0,4) as explained.
Here is the slope-intercept form, it might benefit you in some questions!
where m = slope and b = y-intercept.
Hope this helps! :)
Step-by-step explanation:
42+5x+7x+6=180 (sum of angles in straight line is 180)
- 48+12x=180
- 12x=180-48
- 12x=132
- x=132/12
- x=11
now m <CBE =7x+6=7×11+6=77+6=83
