Answer:
40/76 or 10/19 or 52.63% (they are all equivalent)
Step-by-step explanation:
there are 76 parking spaces in total
30 parking spaces have numbers that are less than 31 (1 - 30)
that means that there are 76 - 30 = 46 spaces that are numbered 31 or higher
so the probability that Jillian parks on a parking space with a number ≥ 31 is 40/76 or 10/19 or 52.63%

Answer:
B. 121
Step-by-step explanation:
1×3=3
3×3=9

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:
Step-by-step explanation:
The formula of a surface area of a cylinder:
r - radius
H - height
We have r = 40mm and H = 50mm. Substitute:
The angle will be 22 degrees since anything bigger that 90 degrees wont work.
