Answer:

Step-by-step explanation:

Ok so first you need to know how to calculate the volume of a cylinder

I will put the formula here: V=πr2h

Since pi is equal to 3.14 as said in the problem we can simply divide 282.6 by pi, the radius and 2

That is equal to 282.6/3.14*3*2

A little calculation shows that, the answer is 15

Hope this helps :)

Identify all solutions for a triangle with A = 38 degrees b = 10, and a= 8. Round to the nearest tenth.

rjkz [21]

Answer:

A = 38°

B = 50.32°

C = 91.68°

a = 8

b = 10

c = 12.77

Step-by-step explanation:

The first thing is to find the angle B, like this:

sin B = b * sin A / a = 10 * sin (38 °) / 8

sin B = 0.77

B = arc sin (0.77)

B = 50.32 °

For angle C, it would be:

C = 180 - 38 - 50.32

C = 91.68 °

Side c, we calculate it like this:

c = a * sin C / sin A = 8 * sin (91.68 °) / sin (38 °)

c = 12.77

The total land area of the world is about fifty-seven million, two hundred eighty thousand square miles. Write that number

expeople1 [14]

The total land area of the world is about fifty-seven million, two hundred eighty thousand square miles is 57, 280, 000 square miles

<em><u>Solution:</u></em>

Given that, we have to write the given words in number

The total land area of the world is about fifty-seven million, two hundred eighty thousand square miles

The number of zeros in million is 6

Here given that 57 million

So, 57 million means 57, followed by 6 digits

two hundred eighty thousand means 280 followed by 3 zeros

two hundred eighty thousand = 280 thousand

Thus the number is: 57, 280, 000
