Area of a circle = PI x r^2
Area = 3.14 x 11^2
Area = 3.14 x 121
Area = 379.94 square cm.
Answer:
it looks like -7
Step-by-step explanation:
i just went to x=-4 and went to the nearest point from there
hope this is correct and helps
Answer: 10 verticesTo make a full circle(360 °), the number of 40° lines you need will be: 360/40=9 lines. So, the base of the pyramid would be made of 9 lines.Pyramid has a base and sides. The sides number is equal to the number of lines of the base. Then, the number of faces/vertices would be: 1 + 9= 10
If the question saying literally 40 edges(not degrees), then the pyramid base would be 40 lines. In this case, the number of vertices would be: 1+40=41
Knowing that a square gives the optimum area;
120=s²
√120=s
√2×2×2×5×3=s
2√2×3×5=s
2√30=s
Therefore, the length should be ≈10.95"
Hope I helped :)
Efficiency = (output)/(input).
This could also be written as
efficiency= output/(output+losses)
or
eff=(input-losses)/input
