A model of a soccer ball is made up of regular pentagons and hexagons.

Monica [59]

<em>An </em><em>apothem</em><em> is a line from the center of a regular polygon at right angles to any of its sides.</em>

<u>For part A</u>,

We want to find area of pentagon (5 sided figure) given apothem is 1.38 in and side length as 2 inch.

If we look at the picture shown (attached), we can see that a triangle is formed. What is the area of this triangle?

$A=0.5bh\\A=0.5(1)(1.38)\\A=0.69$ square inches

<u><em>How many such triangles are there in a pentagon? 10. So we multiply 0.69 by 10 to get total area of pentagon.</em></u>

Area of Pentagon = $0.69*10=6.9$ square inches.

<u>For part B</u>,

We want to find area of hexagon (6 sided figure) given apothem is 1.73 in and side length as 2 inch.

If we look at the picture shown (attached), we can see that a triangle is formed. What is the area of this triangle?

$A=0.5bh\\A=0.5(1)(1.73)\\A=0.865$ square inches

<em><u>How many such triangles are there in a hexagon? 12. So we multiply 0.865 by 12 to get total area of hexagon.</u></em>

Area of Hexagon = $0.865*12=10.4$ square inches.

ANSWER:

Area of Pentagon is 6.9 square inches.

Area of Hexagon is 10.4 square inches.

Answer:

$Product = \frac{3}{5}ab$

Step-by-step explanation:

Given

$-\frac{3}{7}a$

$-\frac{21}{15}b$

Required

The product

The product is:

$Product = -\frac{3}{7}a * -\frac{21}{15}b$ '

Cancel out the negative signs

$Product = \frac{3}{7}a * \frac{21}{15}b$

Simplify fractions

$Product = \frac{1}{7}a * \frac{21}{5}b$

$Product = \frac{1}{1}a * \frac{3}{5}b$

$Product = \frac{3}{5}ab$
