Find the surface area of the closed hemisphere

Mathematics
2 answers:
V125BC [204]3 years ago

Diameter = 8 yards so the Radius = 4 yards:

 Area of a sphere = 4π.R² and hemisphere = 2π.R²

Area of hemisphere = 2.π.(4)² = 32.π
But note we didn't calculate yet the are that closes this hemisphere:
Area of the cicle = π.R² = π.(4)² = 16.π, so the surface area of the hemisphere is 32π + 16π = 48.π (Or =150.8 yard²)

Solve this system of linear equations. Separate
Tems11 [23]

Answer:

(-7,-4)

Step-by-step explanation:

There are 2 different ways to solve a system of equations and the one I'm going to show you will work for all systems.  To start we will solve one of the equations for either X or Y it doesn't matter which one so I will choose the second one.  Divide both sides by negative 4 and you will have the solved equation.  x=1+2y Now we know what x equals so we can plug "1+2y" into the other equation where we see an X and we will get -8(1+2y)=24-8y and since we only have one variable now we can solve to get what Y is.  The first step is distributing -8-16y=24-8y now lets put the Y's together on one side and the numbers together on the other -32=8y and just divide both sides by 8 to get the value of Y -4=y  Now that we have Y we can plug -4 into either equation as Y to get the value of X I will use the second equation.  -4x=-4-8(-4) and solve for X -4x=-4+32  -4x=28  x=-7 So now we have x and y and we can write it as out solution (-7, -4)

I hope this helps and please don't hesitate to ask if there is anything still unclear!

I can Multiply a 11x6 matric by a 6x7 matrix. The resulting matrix will be ??? Can somebody help me
Bumek [7]

Answer:

The resulting matrix will be 11 * 7

Step-by-step explanation:

Given

Matrices 11 * 6 multiplied by 6 * 7

Required

The dimension of the resulting matrix

When a matrix a * b is multiplies by a matrix b * c, the resulting matrix will be: a * c

In this case:

a * b = > 11 * 6

b * c => 6 * 7

So, the resulting matrix will be:

a * c => 11 * 7
