Answer:
1/2 π × d + d where d is the diagonal
Step-by-step explanation:
The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle you need to go half way around the circle and then across a diagonal to get back to where you started so the perimeter is 1/2 π × d + d.
Answer:
A
Step-by-step explanation:
The number of different combinations is the number of different type of each items multiplied together.
To select bundles of "backpack", "binder", "pencil", & "notebook", we see how many different type of each are there and just multiply them. Hence:
"There are 5 types of backpacks, 5 types of binders, 3 types of pencils, and 2 types of notebook paper"
So, 5 * 5 * 3 * 2 = 150
The correct answer is A
1. 3n
2. 9x
3. 9wx
4. 5ac^2
5. 8wx^2
6. 4a^2 c
Answer:
The angle is 35 degrees
Step-by-step explanation:
Since this is an isosceles triangle, we know that the two remaining angles must be the same. Set those angles equal to x. Now, we can solve for x by adding those two angles to the third angle and setting equal to 180.
x + x + 110 = 180
2x + 110 = 180
2x = 70
x = 35
Answer:
6.6 inches
Step-by-step explanation:
4.1 times 3 = 12.3
2.2 times 3 = 6.6
