Answer:
D) The circle is centred at (-8,3) and has a diameter 20
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the circle
( x + 8)² +( y-3)² = 100
⇒ ( x + 8)² +( y-3)² = 10²
Standard form of the circle ( x-h)² +(y-k)² = r²
Centre of the circle (h , k) = (-8 , 3)
Radius of the circle r = 10
Diameter of the circle 'd' = 2r = 2(10) =20
<u><em>Final answer:-</em></u>
The circle is centred at (-8,3) and has a diameter 20

Answer:
The area is 7850 square inches
Step-by-step explanation:
Given the circumference, we want to calculate the area
mathematically, the circumference is;
C = 2 pi r
So r is C/2 pi
Area = pi * r^2
Substitute value for r from circumference;
Area = Pi * c^2/4pi^2
Area = C^2/4pi
Area = 314^2/4 * 3.14
Area = 7850 Inches square
Answer:
Yes, because that three cannot be divided ➗
Okay, let's explain each option to better understand it.
A. The ratio is 2:0.25. When we multiply both sides by 4, we find the ratio 8:1. Option A is not the answer
B. To make 8 bags, she needs 0.5 cups of pecans. Knowing that 16/8 = 2, 0.5*2 = 1. Option B is correct.
C. She requires 2.5 cups of crackers for 8 bags. Knowing that 24/8 = 3, 2.5*3 = 7.5. Thus, Option C is not the answer.
D. She needs one cup of raisins to make 8 bags. She needs 2 cups to make 16 bags, not 1.5.
We can safely say that Option B is correct
