The area of the blue outer ring is given by the area of the entire circular archery less the area of the inner pink circle.

The area of a circle is given by

Area=\pi r^2, where r= \frac{d}{2}, r is the radius, d is the diameter.

Therefore, the area of the outer blue ring is given by:

Area=\pi\left( \frac{24}{2} \right)^2-\pi\left( \frac{6}{2} \right)^2 \\  \\ =\pi(12^2-3^2)=\pi(144-9) \\  \\ =135\pi\ in^2

Let f(x) = - 10x + 9 and g(x) = x2 + 12 <br>Find f( - 4)/g( - 4)​
Reptile [31]

Answer:

\frac{49}{28}

Step-by-step explanation:

Evaluate g(- 4) and f(- 4) by substituting x = - 4 into g(x) and f(x), that is

f(- 4) = - 10(- 4) + 9 = 40 + 9 = 49

g(- 4) = (- 4)² + 12 = 16 + 12 = 28

Then

\frac{f(-4)}{g(-4)} = \frac{49}{28} = \frac{7}{4}

What is the radius of a sphere with a volume of 4.5π cubic centimeters?
Snowcat [4.5K]
V=(4/3)pir^3
4.5pi=(4/3)pir^3
divide both sides by pi
4.5=(4/3)r^3
times 3/4 both sides
3.375=r^3
cube root both sides
1.5=r
radius is 1.5cm
