What’s the original volume

V = 1959.75ft²

Step-by-step explanation:

The volume is equal to the height of the barrel times (π × r²)

V = h(πr²)

V = 10.8(π × 7.6²)

= 10.8(π × 57.76)

= 10.8(181.46)

V = 1959.75ft²

correct

step-by-step explanation:

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.
