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]

<u>Packing boxes</u> are<u> similar shapes</u> with the <u>coefficient of similarity</u> 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
