We know that
area of the circle=pi*r²
if 360° (full circle) has an area of-------------> pi*r²
110°------------------------------> 40 units²
pi*r²=40*360/110--------> pi*r²=130.91------> r²=130.91/pi-----> r²=41.69
r=6.46 units
the answer is
the radius is 6.46 units
<em><u>Total Cost : 1800</u></em>
<u><em>12 dollars * 16 hours = 192 dollars earned</em></u>
<u><em>0.2 percent * 192 = 38.4 dollars saved</em></u>
A.<u><em>She earns 192 dollars every week</em></u>
B. she will save <em><u>38.4 dollars * 7 weeks = 268.8 </u></em> dollars in a week.
C. 7 days times 4.3 weeks = 30.1 days. <em><u>30.1 days * 38.4 = 1,155.84 dollars every month.</u></em>
D. it will take her about <em><u>2 months</u></em> to save the money. <em><u>To be exact: 1.6 months.</u></em>
Hope this helped!
Download photo-math on ur phone and take a picture of the equation. it should tell u the answer.
Answer:
Step-by-step explanation:
Find the area of the square - area of 4 sectors
We'll use the formula to find one sector area
where r is the radius of one sector and x is the angle in radians
Since each angle is in a square, the angle of the sectors is 90 degrees.
Convert degrees to radians
The radius of one sector is given by 70mm/2=35mm
One sector area:
Area of all 4 sectors:
Area of the square:
Hence, Area of square - 4 Sectors:
Answer:
