What is a radius of this circle D=10

Mathematics
1 answer:
Orlov [11]3 years ago
5 0

THE RADIUS OF THE CIRCLE IS 15.7

To find the radius, we'll have to find, the CIRCUMFERENCE FIRST.

Circumference of a circle = π × Diameter

= π (3.14) × Diameter (10)

= 3.14 × 10

= 31.4

So, the circumference is 31.4

The RADIUS is HALF OF THE CIRCUMFERENCE.

Radius = 31.4 ÷ 2

= 15.7

THEREFORE THE RADIUS OF THE CIRCLE IS 15.7

Use the identity a^3+b^3=(a+b)^3−3ab(a+b) to determine the sum of the cubes of two numbers if the sum of the two numbers is 4 an
olga55 [171]

Your identity says ...

... sum of cubes = (sum)³ -3(product)(sum)

... = 4³ -3·1·4

... = 64 -12 = 52

_____

The two numbers are 2±√3, and the sum of their cubes is indeed 52.

What value of y makes y + (4 - 2y) = 2 true?
BlackZzzverrR [31]

Answer:

y = 2

Step-by-step explanation:

Given

y + (4 - 2y) = 2 ← remove parenthesis on left side

y + 4 - 2y = 2, that is

- y + 4 = 2 ( subtract 4 from both sides )

- y = - 2 ( multiply both sides by - 1 )

y = 2
