area = pi X radius squared
so area = 3.14 x 124^2
= 3.14 x 15376 = 48,280.64 square centimeters.
Answer: 8
Step-by-step explanation:
4 is the base. 8 are the sides
f(x) = -720h + 10080
10080 is the total amount of water in the pool, 720 is the amount of water you lose each hour.
"h" is the number of hours the pool has been draining, and since you know the pool has been draining for 12 hours, you can plug in 12 for "h".
f(x) = -720h + 10080
f(x) = -720(12) + 10080
f(x) = -8640 + 10080
f(x) = 1440
After 12 hours of draining, 1440 is the amount of water left in the pool. (I don't know the units [ex: gallons, etc.])
Answer:
5b+1c=3b+5c
Step-by-step explanation:
Let's use the variable c for the circles and b for the boxes.
The weights are the same on both sides, so count the boxes and circles on each side.
There are 5 boxes and 1 circle on the left side. The left side of the equation says 5b+1c.
There are 3 boxes and 5 circles on the right side. The right side of the equation says 3b+5c.
And since the 2 sides are equal, you split the 2 sides of the equation with =.
5b+1c=3b+5c
