Answer:
The diameter is twice that, or approx. 7.90 units.
Step-by-step explanation:
the equation for the volume of a cylinder of radius r and height h is
V = πr²h. Here we need to calculate the diameter after having found the radius. Solving V = πr²h for r², we get:
V
r² = -----------
πh
Substituting the given values, we obtain for r² the following:
145 units³
r² = ------------------------ = 15.6 units²
3.14159(5 units)
Taking the square root of both sides, we get:
r = √15.60, or approx. 3.95 units.
The diameter is twice that, or approx. 7.90 units.
A suitable calculator can row-reduce the augmented matrix.

Answer:
10 degrees
Step-by-step explanation:
1.) every triangle has angles that add up to 180 degrees
2.) a right triangle has a right angle and two acute angles
3.) right=90 degrees; acute=<90 degrees
4.) 90+80=170
5.) 180-170=10
<u>Answer</u>
1.156 × 10⁰
<u>Explanation</u>
In indexes,
a⁰ = 1 ⇒ ㏒aⁿ = ㏒1
n㏒a = ㏒ 1
n = ㏒1/㏒a
but ㏒1 = 0
n = 0/㏒a
= 0
∴ So to represent 1.156 to the power of 10 it will be;
1.156 = 1.156 × 10⁰
