Answer:
If the diameter is 18 then the radius r=9 so the area is:
πr2=81π≅254.469
Step-by-step explanation:
Explanation:
The area of a circle is given by the formula πr2 where r is the radius.
2+2-1=3
2+2=4
And 4 minus 1 equals 3
Answer:
108 kilometers per hour = 30 meters per second
So, 108 kilometers per hour = 108 × 0.27777777777778 = 30 meters per second.
Answer:
r
Step-by-step explanation:
we know this because it is the only part of the graph that is moving downwards, meaning its decreasing. P is an example of increasing, Q is 'neutral' and s is also increasing.
32+33=65
60/2 is 30, so they have to be in their thirties. Then 2+3=5, therefore they must be 32 and 33
