Answer:
(2A /h) - b1 = b2
Step-by-step explanation:
A = 1/2 h ( b1 + b2)
Multiply each side by 2
2A = 2*1/2 h ( b1 + b2)
2A = h ( b1 + b2)
Divide each side by h
2A/h= h/h ( b1 + b2)
2A/h= b1 + b2
Subtract b1 from each side
2A /h - b1 = b2
To the nearest whole number would be 7
For easier comparison, convert all amounts to grams:
30 oz * 28.3 grams = 849 grams
1.6 lb * (16 oz/1lb) * (28.3 grams) = 724.48 grams
800 grams
Comparing the three quantities, the highest is 30 oz (849 grams); next is 800 grams, then 1.6 lb (724.48 grams)
2×11 or do you have to use all the numbers
Area=pir^2
d/2=r
given
d=18
d/2=18/2=9
area=pi9^2=81pi mm²
the exact value is 81π mm²
