Answer:

1. 523 cm^3

2. 1.6 ft

Step-by-step explanation:

1. Formula for volume of a sphere is (4/3)(pi)(r^3)

r = 5

(4/3)(3.14)(5^3) ≈ 523

2. Formula for volume of a cone is (1/3)(pi)(r^2)(h)

(1/3)(3.14)(1^2)(2) ≈ 2.0933

Plug this into the formula for volume of a sphere and find r.

2.093 = (4/3)(3.14)(r^3)

r ≈ 0.7937

Multiply by 2 to get the diameter, which is the height of the spherical barrier.

r * 2 ≈ 1.6

CAN SOMEONE HELP PLZ AND EXPLAIN BEC IF DONT DO GOOD I CANT GO TO MY DADS HOUSE THIS WEEK END

Hello!

6.
Since the area is that of a square, you know that all side lengths are the same. 

Area is base times height (A = bh), but since base and height are the same for a square, you get the formula A = a².

A = a^{2}
144 = a^{2}
\sqrt{144} = a
12 = a

The length of the side of a square with an area of 144 in² is 12 in.

7.
Rational number.

This is a right triangle; use the Pythagorean Theorem to find missing lengths of right triangles. Pythagorean Theorem: a² + b² = c², where c is the hypotenuse of the triangle.

Plug in your leg lengths:

a² + b² = c²
8² + x² = 21²
64 + x² = 441
x² = 377
x = 19.4
