Find the area of all shaded regions. Give your answer as a completely simplified exact value in terms of pi. (no approximations)
Ymorist [56]

The area of the shaded regions is: 44π

<h3>What is the Area of a Circle?</h3>

Area of a circle where "r" is the radius is determined using the formula: πr².

The figure given has three circles, namely:

  • Circle A with radius of 8 cm.
  • Circle B with radius of 4 cm.
  • Circle C with radius of 2 cm.

The area of the shaded regions = <em>Area of circle A - Area of Circle B + Area of Circle C</em>

Area of Circle A = (π)(8)² = 64π

Area of Circle B = (π)(4)² = 16π

Area of Circle C = (π)(2)² = 4π

Thus:

The area of the shaded regions = 64π - 16π + 4π

The area of the shaded regions = 44π

How do I solve this????
Arlecino [84]
Let's say the numbers are "a" and "b"
hmm say "a" is the smaller, and "b" the greater

so "b" is "4 more than 5 times" "a"

so... 5 times "a" is 5*a or 5a
4 more than "that", will be "that" + 4
or
5a + 4

so.. whatever "a" is, "b" is 5a+4

now, their sum is 22, as opposed to "zz" hehe

so       \bf \begin{cases}&#10;a+b=22\\&#10;--------------\\&#10;\boxed{b}=5a+4\qquad thus\\&#10;--------------\\&#10;a+\boxed{5a+4}=22&#10;\end{cases}

solve for "a", to see what the smaller one is

what's "b"?  well, b = 5a + 4
