Answer:
5050
Step-by-step explanation:
S=n*(n+1) / 2
S=100 * (100+1) /2 = 50 * 101 = 5050
Answer:
5×^4
Step-by-step explanation:
I think that is the answer.
Answer:
30.25pi in terms of pi
94.985 In terms of 3.14
Step-by-step explanation:
Okay since the circumference is 11pi we know d = 11.
Meaning r = 5.5
We can solve this in terms of pi or 3.14, for this I will use both.
The formula for an area of a circle is pi*r^2
So,
5.5 * 5.5 = 30.25.
In terms of pi, the answer would be 30.25pi
In terms of 3.14 the answer would be 94.985
