Answer:
I'm pretty sure it is C
Step-by-step explanation:
I’m assuming you just substitute 2 in the equation for x:
4 + x = 4 + 2 = 6
Answer = 6
Plsss im becoming a expert ok peepeepoopoo
SA of a sphere is 4πr² Using a sample of radius 3 the SA would be 36π²
(4πx3²) If we double the radius and make it 6, the SA would be 144π²
So for Surface area, your classmate is correct.
What about the volume? V of a Sphere = 4/3 π r³
Again using 3 the Volume of a Sphere with radius 3 = 4/3 π 27
But the volume of a sphere with radius 6 = 4/3 π 216 which is eight times the volume of the smaller sphere. (27 x 8 =216) So your friend is right about Surface Area but wrong about the volume.
Answer:
Step-by-step explanation:
Conditional Statement: If it is a beagle, it is a dog.
Converse: If it is a dog, it is a beagle. This is a false statement, since a dog can be any other breed (ex. Pomeranian).
Inverse: If it is not a beagle, it is not a dog. Again a false statement, since if it is a different breed, it is a dog despite not being a beagle. For example, it could be a Pomeranian.
Contrapositive: If it not a dog, it is not a beagle. This is true, since if something is not a dog, it won't be any particular breed of dog either (and it won't be a beagle).
