Answer:
(x - 8)^2 + (y + 6)^2 = 4.
Step-by-step explanation:
The general equation is:
(x - a)^2 + (y - b)^2 = r^2.
Plugging in the given values:
(x - 8)^2 + (y - (-6))^2 = 2^2
(x - 8)^2 + (y + 6)^2 = 4.
a = 17.9 meters^2
Given that:
• circumference of circle = 15 meters
T= 3.14
As we know that:
• circumference of circle = 2 nr
By putting values:
•15 = 2 (3.14) r
By simplifying:
• 15=6.28r
Dividing both sides by 6.28 we get:
• r= 2.39 meters
Now for finding area:
• Area = 1 r2
Putting values:
• Area = (3.14) (2.39)*2
By simplifying we get:
• Area = 17 .935 meters’2
So by rounding off radius to nearest tenth:
• radius =r=2.4 meters
Rounding off area to nearest tenth:
• area =a = 17.9 meters’2
Answer:
D
Step-by-step explanation:
Using the Pythagorean Theorem, the side needs to be found by subtracting a to c then square root b to get rid of the square. Round 12.96 to 13
The insurance company pays 80% of $4,400:
0.8*4400 = $3520
Therefor the amount Marge pays is 4400 - 3520 = $880
Note however that $4400 is the cost of annual group insurance, so to find how much she pays monthly we need to divide the amount she pays in one year by 12:
880/12 = $73.33 (correct to two decimal places)
By applying the Pythagorean Theorem, the slant height is given by the formula:slant height=√r2+h2<span>where </span>r<span> is the base radius and </span>h<span> is the altitude.</span>
