Answer:
The volume of the a sphere can be approximated by the rotation of a circle
Step-by-step explanation:
The volume of a sphere can be found by rotating a circle which is the cross section of the sphere about the x axis that is rotating x² + y² = a²
In the process of rotation, each cross section of the sphere generated will have a radius y from which the area of that cross section is π·y² = π·(a² - x²)
Therefore, integrating from +a to -a gives the volume of the sphere as π×[a³ - x³/3]ᵃ₋ₐ which is equal to 4/3·π·r³ (the exact volume of a sphere).
Answer:
What options are there
Step-by-step explanation:
Answer:
Length of rectangle= 13
Step-by-step explanation:
Area= Length × width
91= length × 7
length= 91 ÷7 = 13
Answer:
a
Step-by-step explanation:
g(1)=5
f(g(1))=f(5)
f(5)=2
It’s times by 5 just graph the points on the graph then count how much the rise and run is and then you have your slop
