Zoe is packaging a gift to send in the mail. A smaller gift box is placed inside a similar yet larger packaging box. The empty s

MrRissso [65]

Packing boxes are similar shapes with the coefficient of similarity k=2.1. The volumes of similar shapes are proportional with the coefficient

$K=k^3=2.1^3=9.261.$

Then

$\dfrac{V_{large}}{V_{small}}=K\Rightarrow V_{large}=9.261V_{small}=9.261\cdot 24=222.264\ cm^3.$

The volume of the tissue paper in the packaging box is

$V_{paper}=V_{large}-V_{small}=222.264-24=198.264\ cm^3.$

Answer: $198.264\ cm^3.$

Question 4, plz help ( radius is 6.8)

Kisachek [45]

Answer:

A) 145.3 cm^2

Step-by-step explanation:

The formula for the area of a circle is A = π r^2

So to find the area we would plug the radius of 6.8 into the formula

Area = π (6.8)^2

Area = (3.14) (6.8)^2

Area = 145.27

Area = 145.3
