Answer:
12.5 pi or 39.26990
Step-by-step explanation:
First we can find the radius, which is half the diameter, 5 feet. To find the area of a semi-circle we would find the area of the circle and then divide by 2:
We can substitute what we have:
This gives us:
12.5 pi or 39.26990(Not sure what format you need it in)
Answer:
M
Step-by-step explanation:
because it is equal on either side if you cut a line down the middle of the letter
Answer:
-51
Step-by-step explanation:
-85
+211
-147
+75
-105
=-51
-2y + 5z = -3
y = -5x - 4z - 5
x = 4z + 4
-2(-5(4z + 4) - 4z - 5) + 5z = -3
-2(-20z - 20 - 4z - 5) + 5z = -3
-2(-20z - 4z - 20 - 5) + 5z = -3
-2(-24z - 25) = -3
48z + 50 = -3
<u> - 50 - 50</u>
<u>48z</u> = <u>-53</u>
48 48
z = -1⁵/₄₈
x = 4(-1⁵/₄₈) + 4
x = -4⁵/₁₂ + 4
x = ⁵/₁₂
y = -5(⁵/₁₂) - 4(-1⁵/₄₈) - 5
y = -2¹/₂ + 4⁵/₁₂ - 5
y = 1¹¹/₁₂ - 5
y = -3¹/₂
(x, y, z) = (⁵/₁₂, -3¹/₂, -1⁵/₄₈)
Hello!
First you find what numbers give you the same perimeter
9 + 9 + 6 + 6 = 30
5 + 5 + 8 + 8 = 26
7 + 7 + 4 + 4 = 22
6 + 6 + 8 + 8 = 28
The choice that has the same perimeter is D
The answer is D) 6 centimeters by 8 centimeters
Hope this helps!
