Kelsey has designed a pendant, shown here, that hangs from a chain. She makes pendants by bending silver wire into circles. She plans to sell the pendants at a craft fair, and her goal is to make a minimum profit of $50 at the fair. 1. Kelsey's pendant design connects one circle made from a wire 6 cm long to a second circle made from a wire 8 cm long. Part A The height of the pendant is determined by using the formula for the circumference of a circle, C = πd. Find the total height of the pendant design from top to bottom in terms of π. Then find the height rounded to the nearest tenth of a centimeter. Use 3.14 for π.

4.5 cm.

Step-by-step explanation:

Diameter of each circle will be the height of each circle

The length of the wires are the circumferences of the circles.

Circumference of the first circle is given by

Circumference of the second circle is given by

Total height of the pendant will be

Height of the pendant is

Height of the pendant is 4.5 cm.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
