<h2>
Stella is correct about center and wrong about radius </h2>
Step-by-step explanation:
Equation of circle with (h,k) as center and radius r is given by,
(x-h)²+(y-k)² = r²
Here equation is
x²−8x+y²+2y=5
Changing in to (x-h)²+(y-k)² = r² form
x²−8x + 16 - 16 +y²+2y+1 - 1=5
(x-4)² - 16 + (y+1)² -1 = 5
(x-4)² + (y+1)² = 22
(x-4)² + (y+1)² = 4.69²
Center is (4,-1) and radius is 4.69
Stella is correct about center and wrong about radius

You can answer this problem by solving backwards. she read for 1 hour and 15 minutes so start with 1 hour before she left. 1 hour before 3:23 is 2:23. Now subtract the 15 minutes from that 15 minutes before 2:23 is 2:08.
Therefore the time is 2:08pm.
The formula of the total surface area of the cylinder would be: Base area+ surface area along the circumference.
To find an exact value,we would also have to save 兀and not turn it in other approximate values.
The base area would be:
兀r^2
=兀(50)^2
=2500兀 ft^2
The surface area along the circumferecen would be:
2兀r(base circumference) x height
=2兀50×18
=250兀×18
=4500兀 ft^2
Adding them up,we would then find the total surface area:
4500兀+2500兀
=7000丌 ft^2
Thus,the answer is 7000 丌 ft^2.
Hope it helps!
