Answer:
339.336 m^2
Step-by-step explanation:
Given data
Radius= 6meters
We know that the surface area of a half-sphere is given as
A=3πr^2
A= 3*3.142*6^2
A= 3*3.142*36
A=339.336 m^2
I'm going to say that the answer is $12 for 24 roses
Answer:
Step-by-step explanation:
-x - 1 = x + 3
-2x - 1 = 3
-2x = 4
x = -2
y = -2 + 3
y = 1
(-2, 1)
Answer:quadrupled
Step-by-step explanation:
If the radius of a circle is doubled, the area of the circle will be quadrupled and the circumference will also be doubled. This makes sense because the area of a circle is directly proportional to the square of the radius of the circle (if the radius of a circle is increased x times, its area will be increased to x^2 times the original area), whereas the circumference is proportional to the size of the radius (if the radius of a circle is increased x times, its circumference will increase x times).
AB and CD are interesting lines
Therefore, the angles formed will be equal (vertically opposite angles).
Hence,
Now,
