Step-by-step explanation:

step 1. The circumference (c) of a circle is the diameter of a circle x pi. c = d(pi) = 14pi.

step 2. The area (A) of a circle is the radius of a circle squared x pi. The radius of a circle is 1/2 x the diameter. A = (14/2)^2(pi) = 49pi.

What is the length of TH, when T (10,7), and H (-4,3)?

drek231 [11]

Answer:

TH=14.56

Step-by-step explanation:

Given: T(10,7) and H(-4,3)

Distance formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\text{Length of TH }=\sqrt{(-4-10)^2+(3-7)^2}$

$=\sqrt{14^2+4^2}$

$=\sqrt{196+16}$

$=\sqrt{212}$

$\approx 14.56$

Hence, The length of TH $\sqrt{212}\approx 14.56$

Line segment XY has the coordinates X(–12, –6) and Y(5, 6). What is the approximate length of line segment XY?

malfutka [58]

The approximate length of line segment XY is 20.8 units

<h3>How to calculate the distance between two points</h3>

The formula for calculating the distance between two points is expressed as:

A = √(x2-x1)²+(y2-y1)²

Given the coordinate points X(–12, –6) and Y(5, 6). The distance between them is expressed as;

XY = √(5+12)²+(6+6)²

XY = √(17)²+(12)²

XY = √269 + 144

XY = 20.8

Hence the approximate length of line segment XY is 20.8 units
