Which of the following could be an interior angle measure of a regular polygon?

Scrat [10]

Correct answer is C.

Formula for the sum of interior angles of a regular polygon is $S_n=(n-2)180^o$ , where $S_n$ is the sum of interior angles and $n$ is the number of sides of the regular polygon. Check by substituting the given values.

The measure of an interior angle of a regular polygon is equal to $\frac{S_n}{n}$ .

The equation $\frac{S_n}{n}=\alpha$ , where $\alpha$ is the measure of the interior angle of a regular polygon, must have positive integer solution for n. Check for $\alpha=150^o$ .

$\frac{S_n}{n}=150^o
\\\frac{(n-2)180^o}{n}=150^o
\\(n-2)180^o=150^on
\\180^on-360^o=150^on
\\30^on=360^o
\\n= \frac{360^o}{30^o}
\\n=12$

Two containers designed to hold water are side by side, both in the shape of a

VLD [36.1K]

Answer:

1693.3 ft³

Step-by-step explanation:

The volume of a cylinder is given by; V = πr²h

For container A;

we are given;

Radius;r = 7ft

Height; h = 11 ft

Thus; Volume of container A = π•(7²)•11 = 1693.318 ft³

Similarly,

For container A;

we are given;

Radius;r = 6 ft

Height; h = 16 ft

Thus; Volume of container B = π•(6²)•16 = 1809.557 ft³

Now, since container A was full of water and all of it was pumped into container B, thus, the volume of the water in container B = Volume of container A = 1693.318 ft³

Approximating to the nearest tenth of cubic ft = 1693.3 ft³
