Help Please..!! Will Fan and Medal:))

The diameter of z is 5 in.What is its Area in terms of Pie??

Answer 1

A)2.5 in^2
B)5in.^2
C)6.25 in.^2
D)25 in ^2

Answer 2

\(\large 5\times .5=2.5\)

Answer 3

And 2.5 sqrd is 6.25 so A.

Answer 4

Omggg thank you:)) could you help me with like 2 more??:))

Answer 5

\(\bf \textit{area of a circle}=\pi r^2\qquad r=radius=\frac{diameter}{2}\to \frac{5}{2}\)

solve for "r" to find the radius in terms of \(\Large \pi\) , as opposed to pie, though yours sounds more delicious

Answer 6

So its still A right?? @jdoe0001

Answer 7

well... what did you get for "r"?

Answer 8

hmmmm actually...you're just supposed to .... set it \(\pi \) terms... so \(\bf \textit{area of a circle}=\pi r^2\qquad r=radius=\frac{diameter}{2}\to {\color{brown}{ \frac{5}{2}}}
\\ \quad \\
\textit{area of a circle}=\pi \left({\color{brown}{ \frac{5}{2}}}\right)^2\to \square ?\)

Answer 9

Hold on Whattt?? I dont understand any of that xD

Answer 10

well.. that's the equation for the Area of a circle... in this case, circle "z"

Answer 11

Ohhhh I see now...it showed a different equation because my OS is acting up

Answer 12

\(\bf \textit{area of a circle}=\pi r^2\qquad r=radius=\frac{diameter}{2}\to {\color{brown}{ \frac{5}{2}}}
\\ \quad \\
\textit{area of a circle}=\pi \left({\color{brown}{ \frac{5}{2}}}\right)^2\to \pi (2.5)^2\to 6.5\pi\)

Answer 13

woops darn \(\bf \textit{area of a circle}=\pi r^2\qquad r=radius=\frac{diameter}{2}\to {\color{brown}{ \frac{5}{2}}}
\\ \quad \\
\textit{area of a circle}=\pi \left({\color{brown}{ \frac{5}{2}}}\right)^2\to \pi (2.5)^2\to 6.25\pi\)

Answer 14

So its not 2.5 its 6.5??

Answer 15

:/

Answer 16

just got a typo =(

Answer 17

So it is 2.5??:))
