Answer:
1,440,000
Step-by-step explanation:
1249 is rounded to 1200 because 49 is less than half of 100.
1194 is rounded to 1200 because 94 is more than half of 100.
1200 x 1200 = 1,440,000
Answer:
2 is a factor of 16 but not a multiple of 4.
Step-by-step explanation:
You can multiply 2*8 to get 16, making it a factor, but you cannot multiply 4 by a whole number to get 2.
Answer:
24 π
Step-by-step explanation:
First step is to determine the radius of the base. We have the area, so we can easily determine the radius. The base is a circle, and the area of a circle is given by A = π * r² , so r² = A / π
r² = (36 π) / π = 36
So, r = 6
The lateral surface of a cylinder is given by the following:
L = 2* π * r * 2
Now that we have r, we can easily calculate it:
L = 2 * π * 6 * 2 = 24π, second choice listed
