Let the radius be: r and height be h
volume = πr²
if the radius is halved then radius = r/2
and height is doubled, so height= 2h
volume = πr*r/4*2h = π*r²*h/2
Thus the volume will be halved.
Answer:
The answer is D: 37%
Ignore this answer its wrong, I think. Yeah you're gonna need someone else to figure this out. How do you delete answers on here?
The greatest possible error of 18.9 is 18.95 - 18.85 = 0.1
The greatest possible error of 11 1/8 (11.125) oz is 11.1255 - 11.1245 = 0.001 = 1/1000
Answer:
A. 220
Step-by-step explanation:
To find the total surface area of a square pyramid, you have to find the area of the base and all of the sides and add them together.
To find the area of the base:
Since the base is a square, all we have to do is multiply the length by itself.
10 * 10 = 100
The base is 100 square centimeters
To find the area of the sides:
Since the sides are triangles, we have to multiply the length times the height and divide it by 2.
10 * 6 = 60
60/2 = 30
The area of one side is 30 square centimeters
To find the total surface area:
Add the area of all 4 sides and the area of the base together to find the total surface area.
4(30) + 100 = surface area
120 + 100
220 = surface area
The surface area is A. 220 square centimeters.
