A=p (1+rt)
A future value ?
p Principle 900
R interest rate 0.06
T time 9/12
A=900×(1+0.06×(9÷12))
A=940.5
We are going to need to know the formula for the lateral surface area and volume of a cylinder in order to find our answers. Below are the equations:


is the height
is the radius
Using these formulas, we can solve these problems.


Answer:
sec
Step-by-step explanation:
1/cosin = sec or cosin^-1
Answer: Pi · 2r
Step-by-step explanation:
The standard formula to find the circumference of a circle is Pi times the diameter of the circle. The diameter is 2 times the radius, which is what you're going to use in the formula.
So instead of Pi times the diameter, we have Pi times 2 times the radius. Thus, the formula is Pi · 2r.
Answer:
SA = 4.91 in²
Step-by-step explanation:
A ball is a sphere, and the surface area of a sphere is

If our diameter is 1.25, the radius is half of that at r = .625
Filling in, we have
SA = 4(3.14)(.625)² and
SA = 4(3.14)(.390625) so
SA = 4.91 in²
