And what's the question?

TETSXPREME:

snowflake0531:

Do you know the formula of the area of a circle?

snowflake0531:

Easy question, yes or no lol.

TETSXPREME:

no

snowflake0531:

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

snowflake0531:

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

snowflake0531:

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:

\[5^2\]

snowflake0531:

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

TETSXPREME:

508

snowflake0531:

are you sure you put it into the calculator right.....-_-

TETSXPREME:

no i used my mind C:

snowflake0531:

i-

TETSXPREME:

im to smart for a calculator smh

snowflake0531:

you did it wrong-_-

TETSXPREME:

oh ty C:
