Find the area of the circle. Round your answer the nearest whole number, if necessary.
mina [271]

Answer:

The area of the circle is 314 in^2.

Step-by-step explanation:

10 inches is the radius.

The formula for the area of a circle is pi times radius squared.

So your equation would be: A=\pi (10)^2

10^2 = 100

Then you do \pi or 3.14 times 10 = 314.1592654 or just 314.

Can someone help me with this problem?
dlinn [17]

Answer

7 or 4

because do you see how v is lined 2 I don't remember if you times or divide .I'm going to go with times.

So what is 2 x 10 since V=10

2 x 10=20

Then we are going to divide so what is 20 divided by 5 since e=5

20 divided by 5=4

Next our last step what is 4 + 3=7 and there's are answer.

The answer is divide then this would be the answer.

so V(10) divided by 2=5  divided by e(5) =1 + 3=4

Hope this helps have a great day

Solve the system of equations using substitution or elimination:<br> x = 3y + 6<br> 2x - 4y = 8
dem82 [27]

Answer:

x=0, y=-2

Step-by-step explanation:

Let x=3y+6 be equation 1

and 2x-4y=8 be equation 2

sub equation 1 into equation2,

2(3y+6)-4y=8

6y+12-4y=8

2y=-4

y=-2

sub y=-2 into equation 1,

x=3(-2)+6

x=0

sub is an abbreviation for substitute
