The volume of a sphere is 2,098 pi m^3 what is the surface area of the sphere to the nearest tenth?
Karo-lina-s [1.5K]

Answer:

3139.5 m²

Step-by-step explanation:

the formula for the volume of a sphere of radius r is V = (4/3)πr³.  In this particular case, V = 2098π m³ = (4/3)πr³, and from this we can calculate the radius, r:

       2098π m³

r³ = -----------------  =  (3/4)(2098 = 1483/5

       (4/3)π

Thus r = ∛1573.5 m³ =  11.64 m

Then the surface area is A = 4πr², which in this case is

A = 4(3.14159)(11.64 m)^2 = 1702.6 m² (which is to the nearest tenth).

OLEGan [10]
A = P(1+r/12)^12t, where A = amount after two years, P = Initial amount = $1000, r =apr = 4.2% = 0.042, t = period = 2 years

Then,

A = 1000 (1+0.042/12)^12*2 = $1087.47

A restaurant chef bought potatoes at four different stores. The table shows the amount of the potatoes she bought at each store
hichkok12 [17]

Answer:

The way to answer this question is to find out the price per pound potato by dividing the amount the restaurant chief paid by the number of pounds bought.

Your question lacks details on the pounds bought in the other stores so I will assume these figures and you can use it as a reference.

Restaurant B - 2 pounds

Restaurant C - 12 pounds

Restaurant D - 5 pounds

Price per pound

Restaurant A = 6.60/8

= $0.83

Restaurant B = 3.50/2

= $1.75

Restaurant C = 9.75/12

= $0.82

Restaurant D = 4.80/8

= $0.96

<u><em>Restaurant C </em></u><em>has the lowest price per pound for potatoes. </em>
