The answer to the shortcut is 20m
Area of a circle = pi x radius squared
Radius of a circle is from any point on the circumference to the centre
Diameter is the distance between two points on the circumference with the line crossing the centre
So radius is half of the diameter...
In this example radius is therefore 9mm (half of 18mm)
Square this... 9x9=81
So in terms of pi the answer is 81pi
To get the full answer you would just times pi (3.14) by 81 =254.34
Answer:
In 5 cm there are 50 mm . Which is the same to say that 5 centimeters is 50 millimeters.
Step-by-step explanation:
Let's write the parametric line
(x,y,z) = (0,2,8) + t(5,-1,4)
(5,-1,4) is called the direction vector of the line. It's normal to the plane
5x - y + 4z = constant
We get the constant by substituting the point (3,0,7),
5x - y +4z = 5(3) - 0 + 4(7) = 43
5x - y +4z = 43
Answer:
C
Step-by-step explanation:
The inequality is
40m + 300 > 1,000
subtract 300 from both sides 40m > 700
divide both sides by 40 m > 700/40
(don't reverse the sign. 40 is (+)) m > 70/4
m > 17.5
The answer is C. Madison will not reach her goal in 17 months, but she will be there by the end of the 18th month.
