Answer:

first one:

Area of a circle = π*r²

diameter (they gave) = 30ft

radius = diameter/2 = 15ft

π*15²= 706.85834705770347865409476123789‬

to nearest tenth= 706.9 ft

second question:

circumference = 2*π*r or d(diameter)*π

diameter = 30ft

30*π = circumference = 94.247779607693797153879301498385‬

in terms of π = 30π

Can somebody help me with this?
Natasha_Volkova [10]

Step-by-step explanation:

Hey there!

By looking through figure, l and m are parallel lines and a transversal line passes through the lines.

Now,

7x + 12° = 12x - 28°( alternate angles are equal)

12°+28° = 12x - 7x

40° = 5x

x =  \frac{40}{5}

Therefore, x = 8°

Now,

12x - 28° + 9y - 77 = 180° ( being linear pair)

12×8° - 28° + 9y -77° = 180°

96° - 28° + 9y - 77° = 180°

-9 + 9y = 180°

9y = 180° + 9°

y = 189°/9

Therefore, y = 21°

<u>There</u><u>fore</u><u>,</u><u> </u><u>X </u><u>=</u><u> </u><u>8</u><u>°</u><u> </u><u>and</u><u> </u><u>y</u><u>=</u><u> </u><u>2</u><u>1</u><u>°</u><u> </u><u>.</u>
