Answer:
Step-by-step explanation:
area of square=5×5=25 u²
P is greater than or equal to 2
10p-8>12
+8 +8
10p>12+8
10p>20
/10 /10
P> or equal to 2
Mario = 3g
Jasmine = 10 more shells than Mario = 3g + 10
Hence, number of shells they collected together
= Mario + Jasmine = 3g + 3g + 10 = 6g + 10
Answer:
Rotate a semicircle 180° about its diameter
Step-by-step explanation:
For common figures, the shape of a figure that revolves about a line which is at the base of the figure to give a 3 dimensional shape is the shape of the cross section of the 3 dimensional figure when the angle of revolution is 180° and half the shape of the cross section of the formed 3 dimensional figure, when the angle of revolution is 360°
The cross section of an hemisphere is a semicircle, therefore, the shape of an hemisphere is formed by rotating a semicircle 180° about the diameter (which is the straight line at the "base") of the semicircle
Therefore;
The correct option that gives the revolution that will generate the hemisphere is;
Rotate a semicircle 180° about its diameter.
