Area of the rectangle: {base times height}
4cm x 8cm = 32cm^2
Area of the triangle: {base times height divided by two}
(4cm x 11cm) : 2 = 22cm^2
Total area = 22cm^2 + 32cm^2 = 54cm^2
You do this and then you do that
Alright!
To solve, all we need to do is <em>subtract the area of the inner circle from the arear of the outer circle.</em>
But first, we need to find the area of both
Key equation: πr²
π = 3.14
Inner cirle area = π13²
π13² = 530.66
Outer cirle area = π21²
I got 21 by adding 8 and 13: both added together makes the radius of the larger circle
π21² = 1,385.74
Now let's <em>subtract. </em>
1,385.74 - 530.66 = 855.08
The area of the blue is = 855.08 yards²

The answer is C. 93.53
The answer is 10/3
The explanation 2 1/3 cu of flour/ 3 1/2 dozen of cookies = X unknown cu. of flour/ 5 dozen cookies
Cross multiply
3 1/2 X = 5 (2 1/3) Change the mixed numbers into improper.
7/2 X = 5 ( 7/3) Solve for "X." Multiply both sides of equation by reciprocal of 7/2, which is 2/7
(2/7 (7/2)X = 5 (7/3)(2/7) X= 10/3 =Just divide 10 by 3. You should get a whole number
