A container for a hanging plant is a half sphere with a diameter of 9 inches. about how much soil does the container hold

190.87 cubic inches

Step-by-step explanation:

A sphere is three-dimensional a ball-shaped object. It's volume is calculated using the formula:

V = 4/3πr^3

Where V= Volume of sphere

π (pie) = 22/7 (constant)

r = diameter ÷ 2 i.e. 9/2 = 4.5inches

Hence, to calculate the volume of the sphere, we slot in the values into the formula;

V = 4/3 × 22/7 × 4.5^3

V = 1.333× 3.142 × 4.5 × 4.5 × 4.5

V = 381.753

Thus, the volume of the sphere is 381.753 cubic inches.

However, according to the question, the container is a hemisphere i.e. half of a sphere. Therefore, to get the volume of soil in the container, we divide the volume of the sphere by 2;

381.753 ÷ 2

= 190.87

Hence, the volume of the soil in the hemispherical container is 190.87 cubic inches (in^3)

2.   2 3/5.

3.   2 1/2.

step-by-step explanation:

6 - 3 2/5

= 6 -   17/5

= 30/5 - 17/5

= 13/5

= 2 3/5 (answer).

5 1/4 - 2 3/4

= 21/4 - 11/4

= 10/4

= 2 1/2 (answer).
