1057.5 should be your answer
Sin(45), or sin(pi/4) = sqrt(2)/2. So sin^2(45)= (sqrt(2)/2)^2, which is 1/2.
Answer:
75.4 square inches
Step-by-step explanation:
The cylindrical block has a height of 4 inches and a radius of 2 inches find the total surface area of the block
The formula for the Total surface area of a cylinder
= 2πr (r + h)
= 2 × π × 2( 2 + 4)
= 75.398223686 square inches
= 75.4 square inches
The total surface area of the cylindrical block is 75.4 square inches.
Answer:
The given statement is true.
Step-by-step explanation:
A basic variable in a linear system is a variable that corresponds to a pivot column in the coefficient matrix.
The statement is true.
This statement is the definition of a basic variable.
We can also say that a basic variables are 'n' variables that can take any value other than zero.
Answer:
The constant of proportionality for the group of boxes is: 25
Step-by-step explanation:
Proportion means that change in one quantity causes change in other quantity. Direct variation means that increase in one quantity causes increase in the other quantity.
Let l be the length and v be the volume
Then according to given statement
V∝l
Removing the proportionality symbol introduces a constant in the equation
Putting V = 325 and l = 13
Hence,
The constant of proportionality for the group of boxes is: 25
