Answer:
Step-by-step explanation:
2πr
Standard form means the ordinary number form, like 12, 234, or 150. :)
To find 32 hundreds in standard form, mulitiply 32 * 100 = 3,200
So 32 hundreds in standard form is 3,200.
The area of circle can be found using the formula πr² and since we know that semi circle is half the circle so its formula will be 1/2πr².
First we will find the radius.
20/2 = 10
Radius is 10.
A = 1/2(3.14)(10)²
A = 157
Hope this helps :)
Answer:
17
Step-by-step explanation:
11 + 17 = 28
17 - 6 = 11
Answer:
Cross sections perpendicular to the base and through the vertex will be triangles. Below, you can see a plane cutting through the pyramid, part of the pyramid removed, and the cross section. You could also take a slice parallel to the base. Cross sections parallel to the base will be hexagons.
