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
The first thing you want to do is get them all into decimal format. You can do this to fractions by dividing the denominator from the numerator. then you organize the decimals into least to greatest.
0.25; 0.479; 0.5; 0.5625
0.25; 23/48; 0.5; 9/16

Answer:
y=2 -7x-4
three linear equations
c=-4 ;4a+b=1 ; 9=a-b
Step-by-step explanation:
Simply assume a standard parabola equation y=a +bx +c
(here a, b, c are three independent variables)
Three coordinates as shown in graph are (0,4), (4,0) ,(-1,5)
Now put these points in the equation of parabola and get three linear equations.
[1] c=-4
[2] 4a+b=1
[3] 9=a-b
Now substitute value of a from equation 2 into 3 in terms of b
a=
9=-b
b=-7
a=2
y=2 -7x-4
