hailey wanted to fill her circular pool with water for the summer how much water does she need to fill her pool that is 6 feet d
Setler [38]
The circle area times the depth gives the volume of a cylinder.

Radius is half diameter = 25 ft

Area circle = π(25)²
= 625π

multiply by depth to find volume.
= 625π(6)
= 11,781

I'd say C. is the closest. I don't round numbers until the end so if you round π to 3.14 it's probably the same

Find the length of side xz give your answers to 3 significant figures
aleksandrvk [35]

Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos29° = \frac{adjacent}{hypotenuse} = \frac{ZY}{XZ} = \frac{12.6}{XZ}

Multiply both sides by XZ

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = \frac{12.6}{cos29} ≈ 14. 4 ( to 3 sig. figs )
