Hey there! :)
The formula for finding area of a circle is: π · r²
<em>Remember that diameter is 2x the radius. To find radius when given diameter, divide by 2.</em>
d = 26
26 ÷ 2 = 13
_____________________________________________________________
r = 13
13² = 13 × 13 = 169
169 × 3.14 = 530.66
The area of the swimming pool is 530.66 ft
Hope this helps :)
Answer:
Step-by-step explanation:
amplitude of oscillation a = 12 / 2 = 6 inches.
time period T = 2 s
b = angular frequency = 2π / T
= 2π / 2
= π
so putting the values in the equation
d = a cos ( b t )
d = 6 cos ( π t )
Evey half hour for example the next time would be 9:30 then 10:30 then 11:30 and so on
It will take 250 seconds for it to reach the bottom. To find this I did 17.5 divided by .07.
125.13
