Step-by-step explanation:
A = pi × r²
A = pi × 13²
A = 530.93 km²
V=(1/3)hpir^2
lets say this is original, undoubled volume
so o=v=(1/3)hpir^2
so for new volume, or n, that is r to 2r, doubled radius
n=(1/3)hpi(2r)^2
n=(1/3)hpi4r^2
n=4((1/3)hpir^2)
remmember that o=(1/3)hpir^2
n=4(o)
it is 4 times the old one

Answer:
B 2(−10x+2y−1)
Step-by-step explanation:
The greatest common factor is 2. Factoring that out gives the factorization shown in choice B.
2(-10x +2y -1)
__
You could factor out -2. Doing that would give ...
-2(10x -2y +1) . . . . . . . doesn't match choice C

Answer:
B. x + 2y = 8 is your answer.
Step-by-step explanation:
So this is what you do:
y = -1/2x + 4 <u>You are going to add -1/2 to the other side.</u>
y + 1/2x = 4 <u>You are going to multiply the equation by 2.\</u>
B. x + 2y = 8 is your answer.
