Answer:
3w² + 10w +8 (C)
Step-by-step explanation:
A rectangle has a length that is 3 times its width, w, in inches. The width is increased by 2 inches, and the length is increased by 4 inches. Which expression represents the area of the larger rectangle?
First, remember that the length of the first rectangle is 3 * w, or 3w.
Now, onto the second rectangle.
The width is increased by 2, so it becomes w + 2
The length is increased by 4, so it becomes 3w +4.
Area is length times width, so the area is
(w + 2)(3w + 4)
Simplify.
3w*w + 4*w + 2*3w + 2*4 =
3w² + 4w + 6w +8
3w² + 10w + 8, or C
Answer:
Area of lid = 804.35 square inches.
Step-by-step explanation:
Given the following data;
Circumference of lid = 32π inches
To find the area of the lid;
First of all, we would find the radius of the lid (circle).
Circumference of circle = 2πr
Substituting into the formula, we have;
32π = 2πr
Radius, r = 32π/2π
Radius, r = 16 inches.
Now, we can solve for the area of the circle using the formula;
Area of circle = πr²
Area of lid = 3.142*16²
Area of lid = 3.142 * 256
Area of lid = 804.35 square inches.
In terms of pie, area of lid = 256π square inches.
Therefore, the measurement which is closest to the area of the lid in square inches is 804.35 or 256π.
