What is the area of a circle with a diameter of 12cm?

36pi

Step-by-step explanation:

area of a circle is pi*radius^2

the radius of a circle w a diameter of 12 is 6 so square 6 to get 36 and then multiply by pi

A=36pi cm^2 or 113.097 squared cm

Step-by-step explanation:

A=pi(r)^2

A=pi(6)^2

A=36pi cm^2

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

a reflection across the x axis and a 90 degree rotation left and right.
