Answer:

The radius is 9 mm

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3  where r is the radius

972 pi  = 4/3 pi r^3

Divide each side by pi

972 = 4/3 r^3

Multiply each side by 3/4 to isolate r^3

3/4 * 972 = 4/3 * 3/4 r^3

729 = r^3

Take the cube root of each side

(729) ^ (1/3) = (r^3) ^ (1/3)

9 = r

The radius is 9 mm

Answer:

  Perimeter: 17 inches

  Area: 8 square inches

Step-by-step explanation:

The ratio of perimeters is the same as the similarity ratio.

  JKLM perimeter / ABCD perimeter = P/68 = 1/4

Multiplying by 68, we get ...

  P = 68/4 = 17 . . . . inches

__

The ratio of areas is the square of the similarity ratio.

  JKLM area / ABCD area = A/128 = (1/4)^2

Multiplying by 128, we get ...

  A = 128/16 = 8 . . . . square inches

__

Perimeter = 17 inches

Area = 8 square inches

What is the radius of a sphere with a surface area of 100πcm2?
blondinia [14]
Surface area of a sphere = 4πr^2
4πr^2=100π
Divide both sides by 4π
r^2=100
r=10
The radius is 10 cm.

The correct answer is: Commutative Property

Further Explanation:

The commutative property states that the order of number doesn't matter and changing the order of numbers or variables will produce the same result.

<u>Commutative Property of Addition:</u>

The Commutative Property of addition means that an expression can be written as a + b = b + a.

<u>Commutative Property of Multiplication:</u>

The Commutative Property of multiplication means that an expression can be written as a • b = b • a

Hence, the correct answer is: Commutative Property

Keywords: Commutative property, addition, multiplication
