Answer:
11494.04cm³
Step-by-step explanation:
Volume of a sphere
V = 4/3πr³
you got a diameter of 28cm, so half of taht is the radius.
r = 14cm
plug in and solve
V = 4/3πr³
= 4/3π(14)³
= 11494.04cm³
It is clear that (AB) is a median, and it is obvious that the angle is 90, thus it is an altitude and a perpendicular bisector
The answer is 6. because a hexagon has 6 sidea
Answer:
16 feet
Step-by-step explanation:
Area of a Triangle: (Base*Height)/2.
Therefore, Base:(2A)/Height =(2*24)/2=16
Area of the square = (9 m)^2 = 81 m^2
The four circular sectors combine to form a circle with diameter 9 m, hence radius 4.5 m.
Area of the circle = π (4.5 m)^2 = 20.25π m^2
Then the area of the shaded region is
81 m^2 - 20.25π m^2 ≈ 17.4 m^2
