Answer:
AREA:
CIRCUMFERENCE:
Step-by-step explanation:
The formula that is used to calculate the area of a circle is:
Where "r" is the radius of the circle.
The formula for calculate the circumference of a circle is:
Where "r" is the radius of the circle.
Then, you need to find the radius. This is:
Substituting the radius, you get that the area and the circumference are:
AREA:
CIRCUMFERENCE:
ANSWER
EXPLANATION
The given binomial expansion is:
Compare this to
we have a=2x , b=-3y and n=10
We want to find the coefficient of the term
This implies that, r=5.
The terms in the expansion can be obtained using
We substitute the given values to obtain;
Hence the coefficient is;
Answer:
31
Step-by-step explanation:
(3*22=66) / 6 + [28n - (4)2=20]
66 /6 = 11+ [20]
11+20= 31
Answer:
x<-10
Step-by-step explanation:
10-2.5x>35
2.5x>10-35
2.5x>-25
x>-25/2.5
x>-10
x<-10
