<u>Given:</u><u> </u>

  • Circle with radius 5cm and 3 cm

<u>To </u><u>Find</u><u>:</u><u> </u>

  • How much bigger is the area of a circle.

<u>Solution:</u>

Area of circle with Radius 5cm

Area of circle = πr²

Area of circle = 22/7 × 5 × 5

Area of circle = 22/7 × 25

Area of circle = <u>78.54 </u><u>cm</u><u>²</u>

Now,

Area of circle with Radius 3 cm

Area of circle = 22/7 × 3 × 3

Area of circle = 22/7 × 9

Area of circle = <u>28.27 cm²</u>

= 78.54 - 28.27

= 50.27cm

Hence,

  • <u>Area of circle is 50.27</u><u>c</u><u>m</u><u> more than that area of circle with radius 3cm</u>

MODELING REAL LIFE A post-and-beam frame for a shed is shown in the diagram. Does the brace form a right triangle with the post-
Rainbow [258]

To find out if the triangle is a right triangle, we must check if the following equation is true:

(15)^2+(20)^2=(25)^2^{}^{}^{}

on the left side, we have:

(15)^2+(20)^2=225+400=625^{}

and on the right side, we have:

(25)^2=625

since on both sides we get 625, we have that the brace forms a right triangle.

For questions 10-11 if l || m, find the values of x and y.
klemol [59]

Answer:

10) 9x - 2° = 5x + 54° (corresponding angles are equal)

9x - 5x = 54 + 2

4x = 56

x = 56/4

x = 14°

10y + 6° = 9x - 2° (linear pair)

10y + 6° = 9(14)° - 2°

10y + 6° = 126° - 2°

10y + 6° = 124°

10y = 124° - 6°

10y = 118

y = 118/10

Sorry, i don't know how to do the 11th question

but hope this helps you!
