Answer:
<em>213,645.6cm³ </em>
Step-by-step explanation:
Area of a cylinder is expressed as;
V = πr²h
r is the radius = 2cm
h is the height = 70cm
Get the volume of one rod;
V = πr²h
V = (3.14)(2)²(70)
V = (3.14)(4)(70)
V = 879.2cm³
one steel = 879.2cm³
243 rods = x
Cross multiply;
x = 879.2 * 243
<em>x = 213,645.6</em>
<em>The company will need 213,645.6cm³ volume of steel to make 243 rods</em>
Answer:
last option is the correct answer
The answer is B. 247.50$, because the 65% of 150$ is 97.5, so 150 + 97,5 = 247.5$.
I believe the answer is 17.
