--> 20 bags
Answer:
a) 16.75 cubic inches
Step-by-step explanation:
Cylindrical mold:
V = πr²h
where V is volume, r is radius, and h is height.
Substituting the known values:
V = π(2 in)²(4 in)
V = 16π in³ = 50.26 in³
Spherical mold:
V = 4πr³/3
Substituting the radius to the equation,
V = 4π(2 in)³ / 3
V = 32π/3 in³ = 33.51 in³
The difference is calculated below:
D = 50.26 in³ - 33.51 in³
D = 16.76 in³
Answer:
Step-by-step explanation:
We know that A and B are complementary angles. So, they must add up to 90°. As an equation:
Since we know their equations, substitute:
Solve for x. Combine like terms on the left:
Subtract 9 from both sides:
Divide both sides by 9:
So, the value of x is 9.
We want to find A. So, let's use the equation for A:
Substitute 9 for x:
Add:
So, the measure of A is 17°.
