Answer:
Step-by-step explanation:
the equation of a circle with a center at (0, 8) and a radius of 9.
To frame the equation of the circle we use center radius form of equation
Where (h,k) is the center and 'r' is the radius
Given center is (0,8) and radius = 9
h = 0 , k= 8 and r= 9
Plug in all the values

Step-by-step explanation:
<h3>Find the dimensions of dining room</h3>
<u>Width</u>
- 4*1/4 in = 1 in
- 1 in ⇒ 1*16 ft = 16 ft, according to scale factor
<u>Length</u>
- 5*1/4 in = 1.25 in
- 1.25 in ⇒ 1.25*16 ft = 20 ft
<h3>Find the
area of dining room </h3>
<h3>Find the
cost of flooring for the dining room</h3>
Answer:
42ft^2
Start by splitting the "trapezoid" into two shapes ; triangle and square.
The triangle is a right triangle, so we can use the Pythagorean theorem to find its bottom side so we can find the unknown length of the square. This will also tell us the base of the triangle.
3^2 + b^2 = 5^2
b = 4
This means the square has the dimensions of 9ft by 4ft.
Multiply 9(4) for the area of the square --> A = b(h) = 9(4) = 36ft^2
Now for the triangle,
A= 1/2(b)(h)
base is 4, height is 3 thus:
A=1/2(4)(3) --> 12(1/2) = 6ft^2
Add the area of the triangle and square for the total area:
36ft^2 + 6ft^2 = 42ft^2
Because 140 is less than 144.
