Answer:
4pi + 8 km
Step-by-step explanation:
the circumference of teh circle is d*pi = 8pi. since this is a semicircle the circumference is 4pi. then the perimeter is 4pi + 8
Answer:
You can not write an equation then because it would just be a vertical line, ex: x=4 or x=-4. I hope this helps!
Step-by-step explanation:
Answer:
71.13
Step-by-step explanation:
The half area of a circle is A = 1/2 * pi*r^2 = 1/2 * pi * 3^2 or 9
The trapezoid is a rectangle and a triangle. Rectangle is 8*6 and the triangle is 6*(11 - 8) * 1/2
The total is 1/2 * pi * 9 + 8*6 + 6*(11 - 8) * 1/2 = 71.13
Answer:
The factored form of this would be (x + 4)(x + 9)
Step-by-step explanation:
In order to determine the numbers in the parenthesis, we need to find numbers that multiply to the constant (36) and add up to the middle term (13). In order to do that, we list the factors of the constant and look for those that add up to 13.
1, 36
2, 18
3, 12
4, 9
6, 6
As you can see, 4 and 9 are the only pair that satisfy the stipulations. So we place them in a parenthesis with x's and express as the following.
(x + 4)(x + 9)
Answer:
The result of -1/4 - 1249 is -4997/4
Step-by-step explanation:
Doing the basic math on the given expression:
Given expression = -1/4 - 1249
= (-1 - 4996) / 4
= -4997/ 4
= - 1249.2
