The area of a circle is 100 square miles. What is the diameter?

adell [148]

Answer:

The diameter of a circle with an area of 100 square miles is 20/√π miles.

Step-by-step explanation:

Area =100 = πr^2.

diameter = d = 2r.

100 = πr^2.

100/π = r^2.

√(100/π) = r.

10/√π = r.

d = 2r.

d = 2 * 10/√π.

d = 20/√π

Complete the point-slope equation of the line through (2,3) and (7,4) <br> y-4=

Anna71 [15]

Answer:

y - 4 = $\frac{1}{5}$ (x - 7)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (7, 4)

m = $\frac{4-3}{7-2}$ = $\frac{1}{5}$

Use either of the 2 points for (a, b)

Using (7, 4), then

y - 4 = $\frac{1}{5}$ (x - 7) ← in point- slope form
