Answer:
Area: 776.7 ft²
Perimeter: 55.1 ft
Step-by-step explanation:
The figure is composed of two semi-circles and a rectangle, solve for the area of each figure:
Two semi-circles (which is one circle because they have the same diameter):
The rectangle:
Add them up to get:
Rounding gives 776.7
Now, the perimeter.
Solve for the circumference of the circle and add only the bases of the rectangle:
And add the two bases:
Rounding gives 55.1
And don't forget to put the units.
The answer is the letter C
Answer:
5,9,10.
Step-by-step explanation:
The factors of 20 that I know of are 2,5,10
The possible square no. is below 10 that is, either 4 or 9

Answer:
88 times
Step-by-step explanation:
The two comes up 20 out of 50 times
We don't know how many times 2 will come up if the die is rolled 220 times. We can, however, set up a proportion
20/50 = x/220 Cross multiply
50x = 20 * 220 Combine the right
50x = 4400 Divide by 50
50x/50 = 4400/50 Do the division
x = 88 times.
