A solid hemisphere A had a radius of 2.8 cm. a) calculate the total surface area of hemisphere A.
give your answer correct to three significant figures.

a larger solid hemisphere B has a volume which is 125 times the volume of hemisphere A

b) calculate the total surface area of hemisphere B. give your answer correct to 3 significant figures.

i would pic false cause it goes down towards negative

step-by-step explanation:

the answer is b.6

step-by-step explanation:

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
