Given:
In the given circle, ∠ADB = 270° and length of ADB = 61.26 m
To find the radius of the circle.
Formula
The formula to determine the radius is given by

Substituting arc length = 61.26,
, we get;



Thus, the radius is 13 m
I think it’s D but I’m not really sure.
Answer:
As you can see, x is a variable in both 3x 2 and 7x, and the variable x is multiplied by a number. In the first term, 3x 2, 3 is multiplied by the variable, so 3 is a coefficient. With 7x, 7 is multiplied by the variable. 7 is therefore a coefficient.
I'm assuming you mean how many mph when you refer to how fast the car was going.
So 300 km = 1.5 hrs
1.) Find the number of km per hour
Since we have the equation 300km = 1.5hr, we can just divide 1.5 (to isolate the number of hours) on both sides.
You should get 200 km = 1 hour
2.) Convert km to miles
To do this, you must know the conversion 1 km = 0.621371192 miles
So to convert 200 km to miles, just multiply 200 x 0.621371192.
You should get 124.274238.
That means the Ferrari drove at a pace of roughly 124 mph :)
