Answer:
1176.679ft²
Step-by-step explanation:
<u>The question is on surface area of a cylindrical fuel tank</u>
Equation for surface area of a cylinder
S.A = 2
rh +2r²
where r is the radius of cylinder and h is height of cylinder
Diameter=7'⇒r=3.5' and h=50'
Surface Area= 2×3.142×3.5×50 + 2×3.142×3.5×3.5
S.A=1099.7+76.979=1176.679ft²
16y=6x+42
16/16y=6x/16+42/16
y= 3x/8 + 21/8
Proportional reasoning is the ability to compare two things using information given, in math, it is most frequently defined as comparing quantities. For something to be proportional, there has to a constant ration of another quantity.
$34 divided by 4 = $8.5 per hour.
$8.5 Times 10 hours = $85
So she would earn $85
