(a)36 = 6
(b)81 = 9
(c)256 = 16
(d)196 = 14
=(-17) - 4
=(-17) + (-4)
=(-21)
Do 13 times 14 times 13 times 5 and then divide by however many sides there are on the shape . I think
Answer:
Step-by-step explanation:
Lets find out first the Area of the rectangle building
A=50*100=5000 ft^2
we have 2 circles with the radius of 42 ft, r=21ft
Acircle=3.14*(21)^2=1384.74
Area of 2 circles=2*1384.74=2769.48
What is not covered by the rings is
5,000.00-2769.48=2230.52, rounded is 2231
Choice A
