Answer:

$\large\boxed{V=128\pi\approx401.92}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2h$

We have r = 4 and h = 8:

$V=\pi(4^2)(8)=\pi(16)(8)=128\pi$

$\pi\approx3.14\to V\approx(128)(3.14)=401.92$

If m∠c=11x+85/3 and x=13 then what type of angle is c please help me with this

GuDViN [60]

Answer:

Acute angle

Step-by-step explanation:

Given that m<C = $\frac{11x + 85}{3}$ , to find out the type of angle angle C is, evaluate the expression given by substituting x = 13, in the expression.

m<C = $\frac{11x + 85}{3}$

m<C = $\frac{11(13) + 85}{3}$

m<C = $\frac{228}{3}$

m<C = 76°

Acute angles are less than 90°.

m<C is less than 90°, therefore it is an acute angle.

Find the measure of a central angle of a regular polygon with 10 sides

Paraphin [41]

Answer:

114 degrees

Step-by-step explanation:

The formula to find the measure of all angles in a regular polygon is $(n-2)180$ , where n = total number of sides.

Thus, we substitute n for 10, and you get:

$(10-2)180=1440$

If the shape is a regular polygon and it has ten sides, meaning all sides are equal, then all you do is divide 1440 by 10, to get the final answer of 114.

A central angle in a regular ten-sided polygon would be 144 degrees.

Find the mean of thw data 11,11,12,13,13,13,14,14,15,15,16,16,18

amid [387]

Answer:

the mean is 13

Step-by-step explanation:

The way to find the mean of a set of numbers is to add all the numbers together and divide the sum by the number of numbers. so 11 + 11 + 12 + 13+ 13 + 13 + 14 + 14 + 15 + 15 + 16 + 16 + 18 / 13 = 13.9

Hey eveyone. Im 7th grade 13 years old. Whenever i am at school i always think people think i smell bad. I dont know if its true

Otrada [13]

Answer:Researchers say a psychiatric condition characterized by a person's mistaken belief that he or she smells bad is vastly under-recognized. Called olfactory reference syndrome, the condition is "probably very common," says Katharine Phillips, MD, of Rhode Island Hospital in Providence. so you might just be thinking thst in your head man. just shower, brush teeth etc... or this could be a possibility...What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process.
