Diameter = 8 yards so the Radius = 4 yards:
Area of a sphere = 4π.R² and hemisphere = 2π.R²
Area of hemisphere = 2.π.(4)² = 32.π
But note we didn't calculate yet the are that closes this hemisphere:
Area of the cicle = π.R² = π.(4)² = 16.π, so the surface area of the hemisphere is 32π + 16π = 48.π (Or =150.8 yard²)
Answer:
<u>aₙ = aₙ₋₁ - 3</u>
Step-by-step explanation:
Given :
First term : <u>33</u>
Common difference = 30 - 33 = <u>-3</u>
<u />
============================================================
Then the formula will be :
<u>aₙ = aₙ₋₁ - 3</u>
J+j-8=48
2j=48+8
2j=56
J=56/2
J=28 julios
28-8=20 Juan
Answer
18 and 54
Step-by-step explanation:
Answer:
87.35%
Explanation:
If the total is 1,032,471, it equals 100%
African Americans are in 901,896
1,032,471=100
901,896 = X
Cross multiply
1,032,471x=90,189,600
Divide
x= 87.35%
Hope you get it!
