Answer:

351.68 cm^2

Step-by-step explanation:

We need to find the area of the frame itself. the radius of the inner circle is 12, but the frame has a radius of 4. You add 12 and 4 and you get 16. The formula for area of a circle is A=πr^2. So A= 3.14 x16^2. Then you have A= 3.14x 256 and you get 803.84. But we only want the area of the frame, so you have to get the area of the inner circle and subtract. You get A= 3.14 x 12^2. 3.14x144 is 452.16. 803.84-452.16 is 351.68. Hope this helped. :)

Answer:

351.86cm²

Step-by-step explanation:

12+4=16

(total radius of the whole circle)

use the formula a= πr² to find area

area of the full circle = π*16² (256 π)

256π - area of the smaller circle

256π -  π*12²

256 π - 144 π = 112πcm² or 351.86cm² (to 2dp)

Hope this helps!!

7x + 9 = 58 i need all the steps

Answers

Answer:

Step-by-step explanation:

7x + 9 = 58

     -9    -9      Subtract 9 from both sides

7x = 49

/7     /7           Divide both sides by 7

x = 7 (this is an apporximation)

Answer:

7

Step-by-step explanation:

1st you need to subtract 9 from both sides like this: 7x+9-9=58-9. and you'll get 7x=49. Then, divide by 7 on both sides like this: 7x/7=49/7. and you'll get x=7.
