Answer:

All i have is the area which is 4.5·π cm² + 18 cm² =

Step-by-step explanation:

Answer:

What is the perimeter

Let's break this up:

Radius: 19

Diameter: 38

Circumference: 119.4

So...

The area of a circle with radius 19 is 1134

A = πr2 = π(d

2

)2 A = C2

4π

π = 3.1415

A = area

C = circumference or perimeter

r = radius, d = diameter

SOLUTION STEPS:

Area of a circle in terms of radius:

Area = π·r2 = 3.14·192 = 1134 square cm(*)

Area of a circle in terms of diameter:

Area = π·(d

2

)2 = 3.14·(38

2

)2 = 3.14·(19)2 = 1134 square cm(*)

Area of a circle in terms of circumference:

Area = C2

4π

= 119.42

4π

= 14256.36

(4·3.14)

= 14256.36

12.56

= 1134 square cm(*)

(*) 1134.1149479459 cm, exactly or limited to the precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

Result in other units of area:

A circle of radius = 19 or diameter = 38 or circumference = 119.4 cm has an area of:

1.134 × 10-7 square kilometers (km²)

0.1134 square meters (m²)

1134 square centimeters (cm²)

1.134 × 105 square millimeters (mm²)

4.3784 × 10-8 square miles (mi²)

0.135625 square yards (yd²)

1.22063 square feet (ft²)

175.77 square inches (in²)

Answer:

[tex]tan(30) = \frac{A}{B}[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find tan(30)

Let the side opposite 30 degrees be A and the side adjacent 30 degrees be B

So [using tangent identity]:

[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

This gives:

[tex]tan(30) = \frac{A}{B}[/tex]

Answer:

3v=70

divide both side by 3

=70/3 or ~23.33333

Yes the Frist question is 15 students

the second question is 5 well I mean if you do it by Khan academy

the third one is well three dozen eggs are cracked, so probably 12?

angles sum: 180(6-2) = 720

50 + 37 + 42 = 129

129 + 5x + 7x - 1 + 3x + 40 = 720

15x + 168 = 720

15x = 552

x = 36.8

check:

129 + 5(36.8) + (3(36.8) + 40) + (7(36.8) - 1) = 720

Correct answer??

180-50 = 130

180-37 = 143

180-42 = 138

Known internal angles:

130 + 143 + 138 = 411

15x + 39 + 411 = 720

15x = 270

x = 18

Answer:

Question unclear.

If the question was about the perimeter of the rectangle, it is calculated as:

= (Length * 2) + (Height * 2)

= (11 * 2) + (6 * 2)

= 22 + 12

= 34 cm

If the question was bout Area, the area is:

= Length * width

= 11 * 6

= 66 cm²

Answer:

Step-by-step explanation:

Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27.  So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

Sorry if this is hard to understand. Good luck! :)

Step-by-step explanation:

6 - 3x = 4 - x - 3 - 2x

6 - 3x = -3x + 1

Add 3x to both sides.

6 = 1

Since the last equation, 6 = 1, is false after doing legal steps, that means that the equation is false and has no solution.

Answer: 0

Answer:

yes

Step-by-step explanation:

if we figure out the difference between the two numbers by subtracting one from the other, if the product comes out positive, then the number you subtracted from is greater, if the product comes up negative, then the number you subtracted from is lesser

say we did 3.13 as our first number

3.13 - 3.12 = 0.01

this means that 3.13 is greater by 0.01, if we switch the two numbers however...

3.12 - 3.13 = -0.01

then that means that 3.12 is lesser by 0.01

i hope this makes sence, working with decimals may get tricky sometimes lol

Yes, 3.13 is greater than 3.12.

A decimal number is a number in which whole number part is separated from a decimal.

We have been given two numbers 3.13 and 3.12 and we have to find the greater number from these two numbers. When two numbers are in decimal then firstly we have to see the digit before the decimal, the number having large digit becomes large. If the digit before decimal is same in both numbers then we have to see whether the first digit after the decimal is greater or not. If this digit is also same then we will move towards left and so on.

In the numbers 3.12 and 3.13, 3 which is second digit after decimal is greater than 2. So 3.13 is greater than 3.12.

Hence 3.13 is greater than 3.12.
