Answer:
0.8k +14
Step-by-step explanation:
See the steps below:)
Answer:
Solution given:
Centre(h,k)=(-5,-9)
radius (r)=7
we have
Equation of a circle is;
(x-h)²+(y-k)²=r²
Substituting value;
(x+5)²+(y+9)²=7²
<u>(x+5)²+(y-9)²=49 is a required equation of a circle</u>.
Answer:
56 inches!
Step-by-step explanation:
Rectangles ABCD and EFGH are concentric, that means that they are almost the same but their sides have a different ratio.
First, lets find the area of EFGH.
1). Area of EFGH = a * b = 4 * 6 = 24 inches
Then we will find the area of ABCD.
2). Area of ABCD = a * b = 10 * 8 = 80 inches.
Now we know the areas of the rectangles, we can find the area of the un-shaded part.
3). Area of ABCD - Area of EFGH = 80 - 24 = 56 inches
So, 56 inches will be your answer.
