First find the circumference of the circle.
Circumference:

Plug in 20 for the radius (r).

= 125.66
The circumference of the circle is 125.66 cm.
Now to find this in meters... there are 100 centimeters in 1 meter.
Divide 125.66 by 100 to find how many meters this is.
125.66 ÷ 100 = 1.26
The circle's circumference is 1.26 meters.
Answer:

Step-by-step explanation:
d = 3 + at^2
-3 | -3

d - 3/a = t^2
√d - 3/a = √t^2
t = √d - 3/a
