What is the approximate circumference of a circle with a radius of 42.1 km? A. 5565.4 km B. 1391.3 km C. 264.4 km D. 132.2 km
Answers
c.264.4 that should answer your question
Circumference of circle = 2*pi*r = 2*22/7*42.1 = 264.4 km
Therefore, the circumference of the circle is 264.4 km
One circular table has a diameter of 9ft, and another circular table has a diameter of 14ft. How much greater is the area of the larger table? round to the nearest whole number.
Answers
Area of circle= πr² r-radius
A1-area of table with diameter 9ft A2-area of circle with diameter 14ft d=2r
A1=π*(4,5)²=20,25π A2=π*7²=49π
A2-A1=49π-20,25π=28,75π=90,275≈90ft²
Equivalent ratios 78:100 to 39:50

Well, they are equivalent, but I'm not sure if that's exactly what you're asking. :)

How many unique triangles can be made where one angle measures 60 and another angle is obtuse
Answers
Hello,
An infinite triangles may be constructed You choice 2 points A and B. Draw a angle of 60° Take the perpendicular from B on [AC) (half line) Every point outside [AH] on [AC) give an obtused triangle.
