Answer:
45.625cm²
Step-by-step explanation:
To solve this, we need to do the area of the circle - the area of the rectangle:
<u>Area of the circle</u>
a = πr² (r is the radius, half the diameter)
a = π × 4²
a = π × 16
a = 16π or 50.265cm²
<u>Area of the rectangle</u>
a = length × width
a = 5 × 1
a = 5cm²
50.265 - 5 = 45.265
Hope this helps!

Answer:
y =
Step-by-step explanation:
Since y is inversely proportional to x the equation relating them is
y = ← k is the constant of proportionality
To find k use the condition when y = 7, x = 9
k = yx = 7 × 9 = 63
y = ← equation connecting x and y
To solve this you need to know that area, or "a" =
. so, since the radius is 1/2 the diameter, it would be a =(3.14)(6)
, so 3.14x36. This = B, 113.04 sq in
