Let r be a radius of a given circle and α be an angle, that corresponds to a sector.
The circle area is
and denote the sector area as
.
Then
(the ratio between area is the same as the ratio between coresponding angles).
.
Answer:
$1500
6% interest
use the formula...
P(1+(r/100))^n
where P=initial amount
r=interest rate
t=time period elapsed
so ... for 5 years we get
$1500(1+(6/100))^5 = $1500(1.06)^5 = 2007.3383664
for 10 years
1500(1.06)^10 = 2686.271544814228043264
468 months = 39 years
1500(1.06)^39=14555.261231781943250017719606544
Answer:
3n + 75

Answer:
3.2 gallons
Step-by-step explanation:
Write a proportion:
1 gallon / 825 square feet = x / 2640 square feet
Solve:
x = 3.2 gallons
Answer:
Step-by-step explanation:
The equation for a cylinder is the radius of the circle times pi squared, multiplied by the height. 3 squared is 9, times pi is 9(pi). If we multiply this by the height, the answer is 90(pi) centimeters in volume.
