Work out the curved surface area of this solid cone. give your answer rounded to 1 DP
1 answer:
The Lateral Area of a cone, or the curved wrapping of the cone, can be found by this formula: 
The "r" stands for radius length, and the "l" stands for slant height (that is the official symbol). We are given that the radius length is 8 so we can plug that in.
The slant height is 17. (Slant height is the distance from the vertex point of a cone to any point on the circumference of its circle base).
8x17

I'm not quite sure what DP is, but if it means exact value leave the pi symbol. Pi is the ratio of the circumference to the diameter, so 3.14 is not necessarily the most exact in all circles. Hope this helps!

The answer for the exercise shown above is the second option, which is: <span>Maximum: 32°; minimum: −8°; period: 10 hours.
The explanation is shown below:
</span> You can make a graph of the function given in the problem above: f(t)=20Sin(π/5t)+12.
As you can see in the graph, the maximum point is at 32 over the y-axis, and the minimum is at -8.
The lenght of the repeating pattern of the function (Its period) is 10.

Answer:
9n^4
Step-by-step explanation:
The divisor and quotient can be interchanged to find the divisor:
Such division is carried out by first finding the quotient of the highest-degree terms:
This value is used to multiply the denominator and subtract that product from the numerator to find the new numerator. The new numerator is zero, so the value that goes in Blank 1 is ...
