Find the total surface area of a hemisphere with a radius 10m. Leave your answer in terms of pi (do not multiply by pi).SA = 3πr2(1 point)Responses500π m2500π m squared200π m2200π m squared300π m2300π m squared400π m2
To find the total surface area, we will use the formula for the surface area of a sphere, which is given by SA = 4πr^2.
However, since we are dealing with a hemisphere (which is half of a sphere), we will only consider half of the surface area. Therefore,
SA = 2πr^2
Plugging in the given radius of 10m,
SA = 2π(10)^2
SA = 2π(100)
SA = 200π m^2
Thus, the total surface area of a hemisphere with a radius of 10m is 200π m^2.
so what the answer
The answer is 200π m^2.
Find the volume of the cylinder. V = π r2 h (2 points)
To find the volume of a cylinder, we can use the formula V = πr^2h, where r is the radius of the base and h is the height of the cylinder.
Plugging the given values into the formula:
V = π( r^2 )h
Now, if you provide the values for the radius (r) and height (h) of the cylinder, I can calculate the volume for you.
