By definition, the surface area of the sphere is given by:
Where,
r: sphere radio
Clearing r we have:
Substituting values:
Then, the volume of the sphere is given by:
Substituting values we have:
Answer:
the volume of the sphere is:
We know that
<span>The regular decagon can be divided into 10 congruent triangles
</span>so
area regular decagon=10*[area of one triangle]
area triangle=b*h/2
where
b=3.25 m
h is the aphotem
h=5 m
area=3.25*5/2----> area=8.125 m²
area regular decagon=10*[8.125]----> 81.25 m²
Area=81.3 m²
the answer is
81.3 m²
well, let's assume a year has 365 days, so 75 days is simply 75/365 of a year. We also know that your loan was $650 and you paid back $680 or namely 30 bucks extra, so the interest on those $650 is really 30 bucks.
Answer:
Rate of change of money in Michael's account will be $20 per week.
Step-by-step explanation:
If we draw a graph for the duration of investment on x-axis and amount in the account on y-axis, ordered pairs for both the conditions will be,
After 6 weeks, amount in the account = $140
Ordered pair : (6, 140)
After 12 weeks, amount in the account = $260
Ordered pair : (12, 260)
Rate of change in hi account per week = 
= 
= 
= $20 per week
Therefore, rate of change of money in Michael's account will be $20 per week.
