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.

What is the value of x?

Talja [164]

Use the Pythagorean theorem. The Pythagorean Theorem uses the following formula:

$a^{2} + b^{2} = c^{2}$

Plug in the known values into the equation:

$a = 6, c = 10$

$6^{2} + b^{2} = 10^{2}$

$36 + b^{2} = 100$

Subtract both sides by 36.

$b^{2} = 64$

Square root both sides to get b by itself.

$\sqrt{64} = 8$

$b = 8$

The value of x is 8.

A flower garden is shaped like a circle. Its diameter is 40yd. A ring-shaped path goes around the garden. The width of the path

stellarik [79]

Answer:

Number of sand bags needed = 124

Step-by-step explanation:

Diameter of garden = 40 yd

Width of path = 6 yd

Diameter of garden with path = 40 + 2 x 6 = 52 yd

We need to find area of path.

Area of path = Area of garden with path - area of garden

$\texttt{Area of path = }\frac{\pi \times 52^2}{4}-\frac{\pi \times 40^2}{4}\\\\\texttt{Area of path = }867.08yd^2$

Area covered by one sand bag = 7 yd²

$\texttt{Number of sand bags required = }\frac{\texttt{Area of path}}{\texttt{Area covered by one sand bag}}\\\\\texttt{Number of sand bags required = }\frac{867.08}{7}=123.86\approx 124$

Number of sand bags needed = 124
