Answer:

Step-by-step explanation:
We will use the co-function identity for sine, where:

Since sin(21)=0.358=cos(x). This means that:

Solve for x. Add x to both sides:

Subtract 21 from both sides:

Hence:

It is the first number line :)

Answer:
Hi there!
The correct answer is: 2.185 in
Step-by-step explanation:
The formula for the volume of cylinder is: V= Base * Height
where base is π * radius²
So given that information, we can first divide 10 on sides to get πr²= 15
then divide pi on both sides to get 4.7746 then square root both sides to get
r=2.185
