Answer:

127.17cm²

Step-by-step explanation:

Area of a semicircle: πr² ÷ 2

d = 18

r = 18/2 = 9

Area of a semicircle: 9²π ÷ 2 = 127.17cm²

What is the equation of a line perpendicular to why=2x-6 that passes through (5,4)
almond37 [142]

Answer:

y = ½(13- x)

Step-by-step explanation:

Step 1. Find the<em> slope (m₁) of the original line </em>

The equation for the original line is

      y = 2x - 6

slope = m₁ = 2

Step 2. Find the <em>slope (m₂) of the perpendicular line </em>

m₂ = -1/m₁     Substitute the value of m₁

m₂ = -1/2

Step 3. Find the <em>equation for the perpendicular line</em>

y = mx + b     Substitute the value of m₂

y = -½x + b

The line passes through (5, 4).  

4 = -½(5) + b     Add 5/2 to each side

4 = -5/2 + b     Add 2 to each side

b = 13/2  

y = -½x + 13/2

y = ½(13 – x)  

In the image, below, the red line is the graph of your original equation.

The blue line passing through (5, 4) is the perpendicular line.

Suppose a circle with center (14, 9) passes through point (16, 12). Which equation represents the circle?
kumpel [21]

Answer:

The equation that represents the circle is (x-14)^{2} + (y-9)^{2} = 13

Step-by-step explanation:

Given the center of circle (14,9) passes through point (16,12)

We know that the equation of circle is

(x-h)^{2} + (y-k)^{2} = r^{2}

where (x,y) is any point on the circle, (h,k) is center of the circle and r is radius of circle.

From given data (x,y) is (16,12) and (h,k) is (14,9). Substituting these values in equation of circle, we get

(16-14)^{2} + (12-9)^{2} = r^{2}

r^{2} = 2^{2} + 3^{2}

r^{2} = 13

Substituting the values of (h,K) and  r^{2} as (14,9) and 13 respectively in equation of circle, we get

(x-14)^{2} + (y-9)^{2} = 13

Hence the equation that represents the circle is (x-14)^{2} + (y-9)^{2} = 13
