Answer:</h3><h3>cos(-t) = -4/9</h3><h3>sec(-t) = -9/4</h3>
Explanation:
Since cosine is an even function, we can say cos(-t) = cos(t) for all values of t. So this explains why cos(-t) = cos(t) = -4/9. No change happens.
To find the secant value, we apply the reciprocal. This is because sec = 1/cos. So that's how -4/9 flips to -9/4.

Answer:
s/2πh =r
Step-by-step explanation:
s=2πrh
Divide both sides by 2πh to isolate r
s/2πh =2πrh /2πh
s/2πh =r
