Answer:
62.8yd
Step-by-step explanation:
formula for circumference of a circle = 2 π r
The perimeter is 4 semi circles, so 2 full circles. The diameter is 10yd and the radius is half the diameter, so the radius is 5yd
working:
2 x π x 5 = 31.4yd
31.4 x 2 = 62.8yd
Answer:

Step-by-step explanation:
So we have the equation:

And we want to solve for g.
First, isolate g. To do so, subtract vt from both sides:

Multiply both sides by 2:

Now, divide both sides by t^2:

Expand:

Simplify the second term:

And we're done!
No because they are straight lines, they cannot curve to intersect more than once, think of a capital X.
