Answer:
#1. 31.4 square units
Step-by-step explanation:
We are solving for the square units and also we are circumference formular
which is C = R x 2) (3.14)
R is 5 but in a case they don't give us the Radius and gives us the Diameter we decide the Diameter by 2 and we will get the radius.
Back to the problem
C = R x 2) (3.14)
C = 5 x 2 x 3.14
C = 10 x 3.14
C = 31.4
Answer:
6.3
Step-by-step explanation:
8.5 - (-4.8)
Let's focus on - (-4.8)
if a negative number is subtracted, it reverses itself
In other words, if a negative number is being subtracted, it is the same as being added as a positive number
So we change the equation to
8.5 + 4.8 = 13.3
Now we subtract 7 from 13.3
Since positive 7 is being subtracted, the rule for -4.8 does not apply to it
13.3 - 7 = 6.3
