the correct answer is x=-4
Step-by-step explanation:
the mistake he made is writing 1/4x=-10 instead of 1/4x=-1
He should have wrote -1 instead of -10
Answer:
yes i believe you didnt mess it up. goodluck mate
Step-by-step explanation:
The answer to <span>9y - 11=7 is y equals 2</span>
The word inscribed means that the sphere is inside the cylinder and its diameter is equal to the height and diameter of the cylinder. The surface area of the sphere is equal to
SA (sphere) = πd²
where d is the diameter.
That of the cylinder is,
SA (cylinder) = πd(h + d/2)
Since h is also equal to d
SA (cylinder) = πd(d + d/2) = 3πd²/2
Therefore, the surface area of the cylinder is approximately 1.5 times that of the sphere.
To get the surface area you must get the area of all of the faces of the shape in question. Then add all those areas together.
The answer is- C 132 cm squared
