A snowball has a radius of 7cm. What is the volume of the snowball?
BabaBlast [244]

Answer:

The volume is 1436.8in^2 .

Step-by-step explanation:

-To find the volume of a sphere, you need the formula:

V = \frac{4}{3} \pi r^3

-Use the radius for the formula:

V = \frac{4}{3} \pi 7^3

-Then, you solve:

V = \frac{4}{3} \pi 7^3

V = \frac{4}{3} × \pi × 7^3

V = \frac{4}{3} \pi × 343

V = \frac{1372}{3} \pi = 1436.755

-Round the answer to the nearest tenth:

V = 1436.8

So, therefore the volume is 1436.8in^2 .

2. Koil and Karry want to order the figures from greatest to least
Tom [10]

Given:

Figures A, B and C.

To find:

The order of the figures and volume of each figure.

Solution:

<u>Figure A:</u>

Length = 10, Width = 2 and Height = 2

Volume of A = length × width × height

                     = 10 × 2 × 2

Volume of A = 40 cubic units

<u>Figure B:</u>

Length = 3, Width = 3 and Height = 1

Volume of B = length × width × height

                     = 3 × 3 × 1

Volume of B = 9 cubic units

<u>Figure C:</u>

Length = 6, Width = 3 and Height = 3

Volume of C = length × width × height

                     = 6 × 3 × 3

Volume of C = 54 cubic units

Order from greatest to least:

54 < 40 < 9

C < A < B

Hence Kurry said the correct answer.

Suppose that you need to build as many chairs as possible. Each chair requires one seat, one back, and four legs. If you have 12
GrogVix [38]

Answer:

  legs limit the number of chairs that can be built

Step-by-step explanation:

The maximum number of chairs that can be built will be the minimum of the number of parts divided by the number of parts needed for each chair, as computed across the different kinds of parts required.

  seats: 12 available, used 1 per chair: 12/1 = 12 chairs possible

  backs: 15 available, used 1 per chair: 15/1 = 15 chairs possible

  legs: 44 available, used 4 per chair: 44/4 = 11 chairs possible

The maximum number of chairs that can be built will be the minimum of 12, 15, and 11. That is, 11 chairs can be built, limited by the number of available legs.
