Given:
plot of land doubles in size.
original plot area 200 by 300 meters
Area = 200m * 300m
A = 60,000 m² original plot area
60,000m² x 2 = 120,000 m²
(200m + x)(300m + x) = 120,000 m²
60,000m² + 200m*x + 300m * x + x² = 120,000 m²
x² + 500x + 60,000 = 120,000
x² + 500x + 60,000 - 120,000 = 0
x² + 500x - 60,000 = 0
x = -b <u>+</u> (√b² - 4ac)/2a
a = 1 ; b = 500 ; c = -60,000
x = -500 + (√500² - 4(1)(-60,000)) / 2(1)
x = (-500 + (√250,000 + 240,000)) / 2
x = (-500 + 700)/ 2
x = 200 / 2
x = 100 meters
(200 + x)(300 + x) = 120,000
(200 + 100)(300 + 100) = 120,000
300 * 400 = 120,000
120,000 = 120,000
So the formula for volume of a cylinder is pi multiplied by radius squared times height
so the volume would be 6,725,063.56 units squared
The greater fraction is 6/11
6/11 = 0.54
1/2 = 0.50
Therefore 0.54 which is 6/11 is greater
Answer:
364
