What is the volume of the figure below?
A. 56.6 cubic units
B. 83.4 cubic units
C. 122.5 cubic units
D. 169.2 cubic units

A) 56.60 cubic units

Step-by-step explanation:

A = πr²/3(h₁ + h₂)

= 3.14ₓ(2.6)²(5 + 3)/3

= 3.14ₓ6.76ₓ8/3

= 169.8112/3

= 56.60 cubic units

a

step-by-step explanation:

the answer is a

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.
