TETSXPREME:
snowflake0531:
Do you know the formula of the area of a circle?
snowflake0531:
Easy question, yes or no lol.
TETSXPREME:
no

Okay...
So, the area of a circle is
pi times radius squared
Do you know what radius and diameter are?
TETSXPREME:
nope
snowflake0531:
|dw:1615496782938:dw|
get that?
snowflake0531:
i drew it terribly but-
Radius is from the center to the circle to anywhere
Diameter is twice the length of radius
Yea?
TETSXPREME:
yeye

So, the question says that the diameter is 10 yards.
What is the radius?
TETSXPREME:
20?
snowflake0531:
Diameter is twice the length of radius
snowflake0531:
Wat is da radius
TETSXPREME:
idk

I-
snowflake0531:
Diameter is twice the length of radius
Since the diameter is 10.... and diameter is twice the length of radius...
wat is 10/2
TETSXPREME:
5?
snowflake0531:
Yes!
snowflake0531:
Okay, so now we use the formula
pi times r^2
What is 5^2

TETSXPREME:
what the hell is r?
snowflake0531:
r = radius
d=diameter
c=circumference
pi= \[\pi\]
snowflake0531:
And so, we are finding the area
3.14 times r^2
r is 5
What is 5^2
TETSXPREME:
10?
snowflake0531:
\[5^2\]

Do you know what exponents are? or have you not learned it yet
TETSXPREME:
25
snowflake0531:
yes~
snowflake0531:
So, then, use your calculator, or pencil and paper if you want *shrug
and multiply 3.14 with 25
