Answer:
28.26
Step-by-step explanation:
area of a circle is (pi)(r)^2
radius is half of the diameter
6/2=3
3 feet is the radius
a= 3.14 (3)^2
=3.14 x 9
= 28.26 feet
Answer:
See below for answers
Step-by-step explanation:
Do you mean 
or 
?
Use the formula 
where 
is the amplitude, 
is the phase shift, 
is the vertical shift, and the period is 
.
Assuming your first case is true, the amplitude would be 
, your period is 
, and your midline/vertical shift is 
.
Assuming your second case is true, everything but the vertical shift stays the same. It would be 
in this case.
Answer:
The Equation is
4x+2y= 200
Then total number of candy bars is
X+Y
Step-by-step explanation:
Shelby made $200 from selling x at $4 each and y at $2 each.
Let's have in mind that x is the number of large candy bars
And y is the number of small candy bars
The equation is simple
The amount it was sold is going to be the coefficient of the numbers we don't Know...
So
Equation is
4x+2y= 200
Then total number of candy bars is
X+Y
Solution:
Let me define pyramid first.A pyramid is a Polyhedron , whose base can be any polygon and it's faces are triangular which meet at a point called vertex.
Volume of Pyramid = 
Side of base which is an equilateral triangle= 4 cm
Area of whole pyramid = 12 square cm
Area of Equilateral triangle having side 4 cm=
cm²
So, Area of three triangle which are faces of pyramid = (12 - 4 √3)cm²
Area of triangle = 
12 - 4 √3= 
Height =
Height=(6-2√3) cm
Volume of pyramid = Area of Equilateral triangle which is it's Base × Height of Pyramid
=4√3 × (6-2√3) cm³
=(24 √3 -24)
= 24 (1.732-1)
=24 × 0.732
=17.568 cm³
Answer:
g = 12.7 cm
Step-by-step explanation:
Here, we want to find the length of the side g
To do this, we shall employ the use of the cosine rule
Mathematically, by using the general form of the rule, we have it that ;
g^2 = e^2 + f^2 -2efCosG
So we have;
g^2 = (9.8)^2 + (3)^2 - 2(9.8)(3) cos 167
g^2 = 162.33
g = √162.33
g = 12.7
