Step-by-step explanation:
We know that
Volume of square pyramid = a² × h/3
=> (12)² × 8/3
=> 144 × 8/3
=> 48 × 8
=> 384 in³
Now,
We need to find ratio for finding the times of the volume
=> 3456/384
=> 9
Hence,
Volume of pyramid B is 9 times greater than the volume of pyramid A
The required value is the angle theta and the value of the cosine of the angle is 0.9659
Given the expression of sine of an angle expressed as;
For us to get the cosine of the angle, we need to get the value of theta first as shown:
Next is to get the value of cos theta
The required value is the angle theta and the value of the cosine of the angle is 0.9659

Answer:
Step-by-step explaunfere:
The circumference of a circle is the distance around the outside of the circle. The diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.
1- C ≈ 50.27 in
2- C ≈ 31.42 in
3- A ≈ 201.06
4- A ≈ 314.16
5- C = 14π = 43.982 ≈ 44 inches
π (Pi) times the Radius squared: A = π r2
or, when you know the Diameter: A = (π/4) × D2
or, when you know the Circumference: A = C2 / 4π

Answer:
x = 1 and y = -3
Step-by-step explanation:
Subtract eqn 1 from eqn 2
11y = - 33
y = -3
Substituting y into eqn 2...
10x - 2(-3) = 16
10x +6 = 16
10x = 10
x = 1
