Lesson 4 KC1

Lesson 4 Ex1 Similar and Congruent Solids A. Determine whether the pair of solids is similar, congruent, or neither. Find the ratios between the corresponding parts of the square pyramids. Simplify. Substitution

Lesson 4 Ex1 Similar and Congruent Solids Answer: The ratios of the measures are equal, so we can conclude that the pyramids are similar. Since the scale factor is not 1, the solids are not congruent. Substitution Simplify. Substitution

Lesson 4 Ex1 Similar and Congruent Solids B. Determine whether the pair of solids is similar, congruent, or neither. Compare the ratios between the corresponding parts of the cones.

Lesson 4 Ex1 Similar and Congruent Solids Answer: Since the ratios are not the same, the cones are neither similar nor congruent. Simplify. Substitution

Lesson 4 Ex2 Sports A. Softballs and baseballs are both used to play a game with a bat. A softball has a diameter of 3.8 inches, while a baseball has a diameter of about 2.9 inches. Find the scale factor of the two balls. Answer: The scale factor is about 1.3:1. Write the ratio of the corresponding measures of the balls. Substitution Simplify.

Lesson 4 Ex2 Sports B. Softballs and baseballs are both used to play a game with a bat. A softball has a diameter of 3.8 inches, while a baseball has a diameter of about 2.9 inches. Find the ratio of the surface areas of the two balls. If the scale factor is a:b, then the ratio of the surface areas is

Lesson 4 Ex2 Sports Answer: The ratio of the surface areas is about 1.7:1. Simplify. Theorem 13.1

Lesson 4 Ex2 Sports C. Softballs and baseballs are both used to play a game with a bat. A softball has a diameter of 3.8 inches, while a baseball has a diameter of about 2.9 inches. Find the ratio of the volumes of the two balls. If the scale factor is a : b, then the ratio of the volumes is
