Ah! I love these questions!

To find the area of the shaded region, you must find the area of the circle. Then, you must find the area of the triangle inscribed in the circle. Lastly, you must subtract the area of the triangle from the area of the circle.

Area of Circle: \pi x r^{2}
=\pi x 10^2
=\pi x 100
Usually these problems will not require you to convert pi into a decimal, but if it does, then the area of the circle would be 314. 

Area of Equilateral Triangle: \frac{ s^{2} \sqrt{3} }{4}
To find the side, draw a perpendicular line from the center to a side of a triangle. This line will create two more triangles inside the big triangle. You will notice how in these smaller triangles, the angles are 30, 60, 90. From that we can deduce that half the length of a side is 5\sqrt{3} because of the 30, 60, 90 ratio. Multiply that by 2 to get 10\sqrt{3} as the length of the side of the large triangle. Now substitute this value into the formula above.
\frac{ (10 \sqrt{3})  ^{2} x  \sqrt{3}  }{4} =  \frac{300  \sqrt{3} }{4} = 75 \sqrt{3}

Final Answer: 100\pi - 75\sqrt{3}

A square sandbox has an area of 75 square feet. Estimate the length of one of the sides of the
horsena [70]

Answer:

8.7

Step-by-step explanation:

Since a square has equal side lengths, the formula for area is s^2, where s stands for side. Since we are given the area, s^2=75 square feet. Take the square root of both sides to get s is equivalent to the square root of 75 square feet. When this becomes a decimal, it is 8.66 feet. Since we are supposed to round to the nearest tenths, it rounds up to 8.7 feet per side length

Your graphing the speed your car goes on the interstate from the time you enter the ramp until you arrive at the next exit ramp
inysia [295]

Answer:

1 minute on the x-axis; 10 mph on the y-axis

Step-by-step explanation:

The distance between exit ramps is less than 6 miles and since you are traveling at 70 mph on the highway you should get there in less than 5 mins, so the scale on the x-axis should be 1 minute. Since you have 10 tick marks on the y-axis and will be going at a speed of 70 mph at some point, the scale on the y-axis should be 10 mph (100 mph total). A good scale would be 1 minute on the x-axis; 10 mph on the y-axis.
