Answer:

a = πr²

r = 1/2 (d). so if the diameter is 2, then r = 1

so if you multiply, the area will be 1 π inches

a = π(1)²

a = π

v = 3π inches

because of the error in the area, it led to the error in calculating the volume.

Determine whether the following statement is true or false. Explain your reasoning. Jordan says that when solving the equation 4
Mkey [24]

Answer:

The correct option is;

C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing

Step-by-step explanation:

In other to solve the equation 4·b + 3 = 11, we have;

By the subtraction property of equality, we have;

Firstly we subtract 3 from both sides gives;

4·b + 3 - 3= 11 - 3

Next we apply the division property of equality, we have;

Both sides of an equation remain equal when we divide both sides of the equation by the same, non-number,

Dividing both sides by 4, gives;

4·b/4 = 8/4

b = 8/4 = 2

The solution to the equation, 4·b + 3 = 11 is b = 2.
