33/12 = 2.75 per can
2.75 * 7 = 19.25......so its 19.25 for 7 cans
Our first step is to figure out what formulas are needed for diameter, circumference, and area of a circle.
Diameter is simply twice the size of the radius so:
2 * radius = 2 * 40 feet = 80 ft.
Circumference = 2 * pi * radius = 80 ft * pi
If we say that pi = 3.14, then:
circumference = 251.2 ft.
Area = pi * radius^2 = pi * 1600 ft^2
Once again, if we assert pi = 3.14, then:
area = 3.14 * 1600 ft^2 = 5024 ft^2.
Answer:
37.68 cm
Step-by-step explanation:
The formula for circumference is C= 2* (3.14) r
First you can actually cut 12 by 1/2
12 * 1/2 is 6. This works because 12 is an even number.
2 * 3.14 (6) gives you 37.68 cm.
So i believe the answer is 37.68 cm.
F(x) = 2x + 1 when x <= -5
Now -10 is less than -5 so we plug x = -10 into 2x +1:-
f(-10) = 2(-10) + 1 = -19 answer
Now f(x) = x^2 when -5< x < 5
x =2 is within this range so f(2) = 2^2 = 4 answer
You can calculate the other 3 values by a similar method
YESSS USE THATTTTTTTTTTTT
