(b) 1
(c) 34.765 x 10^-4
(d) 2.56 x 10^2
<u>Explanation:</u>
Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form.
In this case, the scientific notation of 00.0602 will be 6 X 10⁻⁴
1
, 34.765 x 10⁻⁴ and 2.56 x 10² are already in scientific notation form.
You know the formula for calculating the lateral area of a cylinder with a radius r and height h is S=2*π*r*h
So we have S= 2*π*6*20= 240π

Answer:
32.7°
Step-by-step explanation:
Use the formula for law of cosines, for this question we need so solve for angle B, so use...
b² = a² + c² - 2(a)(c)Cos B
We are given a, b, and c, so plug them in...
55² = 90² + 50² - 2(90)(50)Cos B
Now simplify...
3,025 = 8100 + 2500 - (9000)Cos B
-7,575 = -(9000)Cos B (subtract 8100 and 2500 from both sides)
0.841666667 = Cos B (divide both sides by -9000)
Cos^(-1) 0.841666667 = B (use cosine inverse function on calculator)
