What is the volume of a sphere with a surface area of 64cm??
O 167 cm
O 213 cm
0 487 cm
O 85 cm
The volume of a sphere whose surface area is 64cm is approximately 85cm .Thus, the correct answer is option (D)
What is a sphere?A sphere is a three-dimensional equivalent of a two-dimensional circle. A sphere is a collection of points in three-dimensional space that are all the same distance r from a given point. The supplied point is the sphere's center, and r is the radius of the sphere. The earliest known mentions of spheres appear in the work of ancient Greek mathematicians.
The volume of a sphere is calculated as:
Given,
Surface area = 64πcm
The formula for surface area is 4πr^2
So, 4πr^2 = 64π
r= 4cm
The volume (V) of the sphere is:
V = 4/3 π r³
V = 4/3 π (4 cm)³
V = 4/3 π 64 cm³
V = 85.33π cm³
Therefore, 85cm is the correct answer.

Which of the following is NOT a contributing factor to Africa's rapid rate of urbanization?
Better lifestyle
Education
Jobs
Negative population growth
Rapid population growth
Negative population growth is the factor that is NOT a contributing factor to Africa's rapid rate of urbanization. Hence, option D is correct.
What factors that affected the urbanization in Africa ?Urbanization refers to the process by which people move from rural areas to cities or urban areas. In Africa, there has been a rapid rate of urbanization in recent years, and there are several contributing factors to this trend. These factors include:
Better lifestyle: Many people are attracted to the perceived higher standard of living and greater economic opportunities in urban areas.
Education: Urban areas often have better access to education and other services than rural areas, which can also be a draw for migrants.
Jobs: Urban areas typically offer more job opportunities, which can be a major factor in attracting people to cities.
Rapid population growth: The high population growth rates in many African countries can contribute to the rapid rate of urbanization, as more people move to cities in search of opportunities.
Negative population growth, on the other hand, would have the opposite effect and could slow down the rate of urbanization, as there would be fewer people looking to move to cities.
Hence, option D is correct.
