We know that
area of a circle=pi*r²
for r=2 km
area of a circle=pi*2²-----> 12.56 km²
if 360° (full circle) has an area of---------> 12.56 km²
45°---------------------------------> x
x=45*12.56/360-----> x=1.57 km²
the answer is
1.57 km²
Answer:
A
Step-by-step explanation:
When you shift down by 5 units, you are basically -5ing to every value in the bottom part of the chart.
For the bottom of the chart, I get:
0,2,8,14
While the top is
1,2,3,4 as nothing changes here.
The only chart like this is A.
Answer:
5. R = 6
6. D = 22
Step-by-step explanation:
5. The area formula is πr2.
If πr2=36π,
π can be canceled out from both sides.
Then, it is r2=36.
If we square root both sides, we get:
r=6 .
Therefore, the radius of your circle is 6.
6.A = 121 π
A = r² π
r² π = 121 π
r = √ 121 = 11
The diameter: d = 2 r = 2 * 11 = 22 units
6y-8
6y is 6 times y
-8 is 8 less
