Answer:

78.5cm^2

Step-by-step explanation:

Half your diameter to get a radius.

D = 10cm

10 divided by 2 = 5

Pi (3.14)

3.14 x 5^2

3.14 x 25 = 78.5cm^2

Answer:

78.5 cm^2.

Step-by-step explanation:

The diameter d = 10 so the radius = 1/2 * 10 = 5cm.

Therefore the area = π r^2

= π * 5^2

= 3.14 * 25

= 78.5 cm^2.

Find the circumference of a circle if the area is 300 square centimeters.

mr Goodwill [35]

So the formula for a circle is Pie * r^2

If you divide 300 by pie and then Square root it you would get your radius

And once you have the radius you would use the equation of 2pie * r to find the circumfrence.

Answer is 61.38

3x-4y=11 <br>3x+2y=2<br>please help, I need to find what the answer is for x and y

Zielflug [23.3K]

Answer:

I have attached a picture of me solving the equation.

Now you must be wondering how I got the answer, well first simplify the expression in y = mx + b. Then graph it on demos. Do the same thing for the other expression. Pick any point that lies on the line. That is your solution to the equation.

The green line is the expression of 3x - 4y = 11. I simplify the equation in y = mx + b giving me y = 3/4x - 11/4.

The orange line is the expression of 3x + 2y = 2. I simplify the equation in y = mx + b giving me y = -3/2x + 1.

Hope this helps, thank you !!
