Answer:
28.26 m^2
Step-by-step explanation:
Given that the area of a circle is , we have to plug in the value of the radius and simplify. The radius is half the diameter, which is a line that splits the circle into halves. Thus, the radius here is 3. 3^2 is 9, and we can shorten pi to 3.14. 3.14 x 9 is 28.26, so the area of the circle is 28.26 m^2.

<h3>What is the solution of the equation?</h3>
A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.
Let the number of pounds of type A coffee be x and the number of pounds of Type B coffee be y.
According to the question, the equations are,
5.50x + 4.40y = 762.30
x = 4y
So, the solution of the equation is obtained as follows:
5.50(4y) + 4.40y = 762.30
26.40y = 762.30
y = 762.30/26.40
y = 28.8 pounds
x = 4*28.8 = 115.2 pounds

Answer: i think its 10 or 8
Step-by-step explanation:
sorry if im wrong
Option 1 : 20 + 1.25d
option 2 : 2.50d
when will they be equal......so set them equal to each other
20 + 1.25d = 2.50d
20 = 2.50d - 1.25d
20 = 1.25d
20 / 1.25 = d
16 = d.....so they will be equal at 16 dvd rentals
Answer:
answer is C. if im wrong just let me know :3
