Answer:
To solve this we calcuclate the total are then we subtract the 4 rectangles area
total area = length × width =10.5 × 10.5 = 110.25 cm²
the rectangles drawn accurately = 2(.5 × 7)
7 cm²
the rectangles drawn not accurately 2(.5 × 10.5)
= 10.5 cm²
so the shaded area = 110.25 - 7 - 10.5 = 92.75 cm²
Can you please specify your answer
thanks
Answer is parallel lines
Reason - same slope (3x) and different y intercept means they will be parallel lines because their slope is the same but they will cross the y axis at different points.
I changed the first equation to y intercept form
y = 3x - 10 to match the other equation
y = 3x - 6
I believe it would be 5/9
<span>arc length = circumference • [central angle (degrees) ÷ 360]
Solving this equation for circumference:
</span>
<span>circumference = arc length / (central angle / 360)
</span><span>circumference = 12 / (85/360)
</span>circumference = 12 / <span><span>0.2361111111
