Angela decides to recycle a large oatmeal container by using it to hold a friends birthday gift. Then she wraps the container in

Deffense [45]

Answer:

D. 135.37 in²

Step-by-step explanation:

We have that the gift paper consists of two circles and a square.

Thus, we will need to find the area of the circles and the square.

Now, as the diameter of the circle = 4 inches

So, the radius of the circle = $\frac{4}{2}$ = 2 inches

Since, the area of a circle = $\pi r^{2}$

This implies that area of the two circles = $2\times \pi r^{2}$

i.e. Area of the circles = $2\times \pi 2^{2}$

i.e. Area of the circles = $8\pi$

i.e. Area of the two circles = 25.133 in²

Further, one side of the square = 10.5 inches

Thus, the area of the square = $side^{2}$

i.e. Area of the square = $10.5^{2}$

i.e. Area of the square = 110.25 in²

So, the overall area of the gift paper = 25.133 + 110.25 = 135.37 in².

Hence, the amount of paper used by Angela is 135.37 in².

For the inequality y−x>−x2−1, where is the graph shaded and is the curve solid or dotted?

vodomira [7]

The curve will be dotted and upper portion of the graph will be shaded.

<h3>Inequality expression</h3>

Inequality are expressions not separated by an equal sign Given the following inequality

y−x>−x2−1

Equate to zero

y > x^2 + x -1

Since the inequality sign in the given expression is a less than sign, hence the curve will be dotted.

Also, since the inequality sign is a "greater than", hence upper portion of the graph will be shaded.
