Answer:
≈ 30.63 cm²
Step-by-step explanation:
The shaded area is calculated by subtracting the area of the inner circle from the area of the outer circle.
outer circle has radius = 8 ÷ 2 = 4 and inner circle has radius = 5 ÷ 2 = 2.5
shaded area = πr₁² - πr₂² (r₁ is outer and r₂ is inner )
A = π (4² - 2.5²)
= π(16 - 6.25) = 9.75π ≈ 30.63 cm²
The answer would be B and D. This can be found by putting the x and y values into the inequality to find whether or not they are true.
Answer:
Each combo costed $4.95
Step-by-step explanation:
To solve, simply divide 103.95 by 21, and then put a dollar sign. (Most teachers would count no dollar sign as incorrect/points off, so don't forget it!)
103.95 ÷ 21 = 4.95 → $4.95

Answer:
1.)
132 cm - 11 cm = 121 cm
So let the hypotenuse be x and the other leg be (121 - x).
11^2 + (121 - x)^2 = x^2
121 + 121^2 - 121(2)x = 0
x = 1/2 + 121/2 = 61 cm
