c. For D and D' to have the same coordinates the figure must be rotated by 360.
<em>OB = 3 cm</em>
- Step-by-step explanation:
<em>AO = radius = 5 cm</em>
<em>AB = 8cm/2 = 4 cm</em>
<em>Pythagora</em>
<em>OB² = AO² - AB²</em>
<em>= (5cm)² - (4cm)²</em>
<em>= 25cm² - 16cm²</em>
<em>= 9 cm²</em>
<em>OB = √9cm²</em>
<em>= 3 cm</em>

Kayla can make 50 ribbons for the show using 32 feet ribbon
<u>Solution:</u>
Given, Kayla's making ribbons for school spirit day a roll of ribbon is 32 ft long And for each individual ribbon she needs 0.64 ft
