Question

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

Answer 1

4.4cm

Explanation:

in this problem we are expected to solve for the diameter of each circle pendant and add them to get the height of the complete pendant.

we know that the circumference is given as

C=πd

for the small circle

C=6cm

6=3.142d

d=6/3.142

d=1.9cm

for the big circle

C=8cm

8=3.142d

d=8/3.142

d=2.5cm

the height then is 1.9+2.5=4.4cm
