The word inscribed means that the sphere is inside the cylinder and its diameter is equal to the height and diameter of the cylinder. The surface area of the sphere is equal to
SA (sphere) = πd²
where d is the diameter.
That of the cylinder is,
SA (cylinder) = πd(h + d/2)
Since h is also equal to d
SA (cylinder) = πd(d + d/2) = 3πd²/2
Therefore, the surface area of the cylinder is approximately 1.5 times that of the sphere.
Answer:
The answer to your question is time = 20 min
Step-by-step explanation:
Data
Candace = 480 ft/min
time = 5 min
Brother = 660 ft/min
Process
1.- Calculate the distance traveled by Candace in 5 min
distance = speed xtime
= 480 x 5
= 2400 ft
2.- Write the equations to help solve the problem
Candace distance = 2400 + 480t
Brother distance = 600t
3.- Solve by equality
2400 + 480t = 600t
2400 = 600t - 480t
2400 = 120t
t = 2400/120
t = 20 min
4.- I will solve the equation given
480t = 660(t - 112112)
480t - 660t = -112112
-120t = -112112
t = -112112/-120
t = 934 h I think there is a mistake in the formula you
wrote.
Store A answer:
$0.32
Store A explanation:
You divide the cost by the number of ounces, so 3.81 / 12, which equals 0.3175, which rounded to the hundredths place is $0.32
Store B answer:
$0.37
Store B explanation:
You divide the cost by the number of ounces, so 1.10 / 3, which equals 0.3666667, which rounded to the hundredths place is $0.37.
Overall answer:
A
Overall explanation:
The price per ounce at store A is less then the price per ounce at store B.
Hope this helps!!!
Answer:
0=13 NOT TRUE/ Undefined
Step-by-step explanation:
5(y – 4) - 19y = -7(2y+ 1)
EXPAND
5y-20-19y = -14y-7
