Answer:
88 ft^2
Step-by-step explanation:
To find the surface area of a rectangular figure
SA = 2(lw+lh+hw)
where l=length, w= width, h = height
let l=6, h=2, w=4
SA = 2(lw+lh+hw)
= 2 (6*4+ 6*2+ 2*4)
=2 (24+12+8)
=2 (44)
= 88
SA = 88 ft^2
Given,
Diameter of circle=15cm
so, radius= D/2= 15/2
we know that circumference=perimeter
2πr= 2×22/7×15/2=47.1428cm
$7.50 * 18.5 hrs = $138.75
$7.50 * 20 hrs = $150
138.75 + 150 = 288.75
She raises the price by ¢0.75
So now it is $8.25 per hour
(I guessed on a calculator and got it right)
Multiply 8.25 by 35 and you get 288.75
Your answer is 35
