Lessons Apps Membership. Find the cost of plastering the internal surface of the tunnel excluding the floor at the rate of Rs. 14. Using π ≈ 3. The height of the tunnel is modeled by the equation y = − x 2 + 36, where it reaches a maximum height of 36 feet at (0, 36) and is zero at points (6, 0) and (-6, 0). The tunnel is 120 ft long and 30 ft high, as shown below. The tunnel is $$35 \mathrm{m}$$ long. `(2gr)/(pi)` The sides of are the diameters of semicircles as shown. 25 per m 2 . Find the force (in terms of k, Q, and R) on a charge q located equidistant from the five other charges. 3m. qz F Wall af- wall -fluid 982 1b 3370 1b = 982 For J i A corporation building is in the form as shown alongside.
