Answer:
Step-by-step explanation:
The circumference of a circle can be found using the following formula:
where d is the diameter. We are given the radius, so let's find the diameter.
The diameter is twice the radius.
The radius is 15 feet.
Multiply.
Now we know the diameter. Substitute 30 feet in for d.
We are using 3.14 for pi, so substitute it in.
Multiply.
The circumference of the circle is 94.2 feet.
Answer:
B) 60
Step-by-step explanation:
They both equal each other,
5x+15=7x-3
And solve!
15+3=7x-5x
18=2x
X=9
Plug X into the angels.
5(9)+15
45+15
60
Answer:
C=252
Step-by-step explanation:
Given:
x^5y^5
(x+y)^10
Find the coefficient of x^5y^5
To get the coefficient of x^5y^5,
we will put r = 5, in the below given general term.
The general term is : nCr =x^ry^n-r
We get:
Coefficient is = 10C5
= 10!/5!*5!
= 252
The coefficient of x^5y^5 is 252
C. 252
