Answer:
D
Step-by-step explanation:
The area of a circle can be found using:
a=πr^2
We know that the radius is 10 meters. Therefore, we can substitute 10 in for r.
a=π*10^2
Evaluate the exponent
a=π*100
Multiply pi and 100
a=314.159265359
Round to the nearest tenth: there is a 5 in the hundreth place, which indicates we round up the 1 in the tenths place to a 2.
a=314.2
The area is 314.2 square meters, or choice D
Answer:
77 feet below sea level.
Step-by-step explanation:
Since y is the time the submarine is ascending, we can plug it in for y and find our answer. We can create an equation where D is the depth and y is time ascending: D = -230 + 17y
Substitute 9 for y:
D = -230 + 17(9)
D = -230 + 153
D = -77
The depth of the submarine after 9 minutes will be 77 feet below sea level. Hope this helps, and Brainly will be highly appreciated.
Answer:
Brad in total drove approximately 361 miles.
Step-by-step explanation:
Renting Cost per day of car = $26. 95
Cost per mile= $0.33
So, cost of renting car 3 days = 3 x $26. 95 = $80.85
Total money spent on the trip = $80.85
So, the actual spent money on distance = Total money spent - The renting charge
= $200 - $80.85 = $119.15
So, Distance travelled = 
= 
or, number of miles traveled = 361
So, Brad in total drove approximately 361 miles.
