I need help with this math problem.
katrin [286]

Answer:

The answer to your question is s = 399.5 m

Step-by-step explanation:

Formula

                   s = \sqrt{\frac{3V}{h}}

Data

V = 7 500 000 m³

h = 141 m

Substitution

                  s = \sqrt{\frac{3(7500000)}{141}}

                  s = \sqrt{\frac{22500000}{141}}

                 s = \sqrt{159574.47}

                 s = 399.46 meters ≈ 399.5 meters

Find the area, please help me, having a hard time getting through tonight’s homework. Complex/Compound area. Thanks!
Digiron [165]
Since the bottom shape is a semi-circle, the 3yd is the radius making the triangle's area 7 x 3 / 2 = 10.5

The semi-circle's area is \pi 3^{2} /2 = 14.14

Combined, you get an area of 10.5 + 14.14 = 24.64yd^{2}
