Answer: 352/105
Step-by-step explanation:
Diameter of the circular disk is
(2−x2)−x2
so that the radius of the disk is the diameter divide by 2
(2−x2−x2)/2.
Integrating V at 1 and -1, we get
V =Z 1−1A dx =Z 1−1π(1 − x2)2
dx = π(x −2/3x3 +1/5x5)1−1
=16/15π
= 352/105
Solve for x:10 - (7 x^2)/3 + X^4/3 = 0
Subtract X^4/3 + 10 from both sides:-(7 x^2)/3 = -X^4/3 - 10
Multiply both sides by -3/7:x^2 = X^4/7 + 30/7
Take the square root of both sides:Answer: x = sqrt(X^4/7 + 30/7) or x = -sqrt(X^4/7 + 30/7)
Answer:
990 square feet
Step-by-step explanation:
To find the total area of the field, we find the area of each plot first, and then multiply it by nine (representing the 9 workers)
Each plot measures 11 feet by 10 feet. Hence, they are rectangular plots.
The area of the plot is:
A = L * B
A = 11 * 10 = 110 square feet
Therefore, the area of the 9 plots is:
9 * 110 = 990 square feet
The area of the field is 990 square feet
