X=13 1/3
So first you have to add 16 +4 = 20. Then, simplify 3/2 to 1.5. Finally divide 20 by 1.5 = 13.333333333, or 13 1/3
Answer:
volume of the hemisphere ≈13.3 m³
Step-by-step explanation:
To find the volume of the hemisphere, we will follow the steps below;
volume of a hemisphere = volume of a sphere/2
= 
πr³ /2
=
πr³
from the question given, the diameter is 3.7 m, but diameter = 2×radius
radius = diameter /2 = 3.7/2 =1.85 m
π is a constant = 3.14
volume of a hemisphere = πr³
≈ ×3.14 ×1.85³
≈13.3 m³
Therefore, volume of the hemisphere ≈13.3 m³
Answer:
there are 100 centimeters in 1 meter
Step-by-step explanation:
Answer:
Option 2 ( 1,-10)
Step-by-step explanation:
The two equations are y = -x²-5x-4 -----(1)
and y = -x²+9x-18-------(2)
To get the solution of these lines we will substitute the value of y form equation 1 to 2.
- x² - 5x -4 = -x²+9x-18
Now by collecting similar terms on each side.
-x² -5x + x²-9x = -18 + 4
-14x = -14
14x = 14
x = 1
By putting the value of x in equation 1.
y = -1 - 5 - 4 = -10
So the solution is (1, -10)
Therefore Option 2 is the correct answer.
Volume of a rectangular pyramid=(1/3)Bh
B=base=120 ft * 30 ft=3600 ft²
h=100 ft
Volume=(1/3)(3600 ft²)(100 ft)=120000 ft³
Answer: 120000 ft³
