Answer:
48.7 I think
Step-by-step explanation:
hears the sender buddy
D = 2r => 12.6 = 2*r => r=6.3
A = π*r^2 = (3.14) * (6.3)^2 = (3.14)*(39.69) = 124.6266 which is approximately 124.63
Hope this helps!
Answer:
C.) 5, 12, 13
Step-by-step explanation:
In a right triangle, the sum of the squares of the two shorter sides must equal the square of the longest side (Pythagoras).
a² + b² = c²
We can test each set of numbers to see which one fits.
A.) 8² + 12² = 16²
64 + 144 = 256
208 ≠ 256
B.) 6² + 7² = 8²
36 + 49 = 64
85 ≠ 64
C.) 5² + 12² = 13²
25 + 144 = 169
169 = 169
The numbers 5, 12, and 13 could represent the lengths of the sides of a right triangle.
D.) 16² + 32² = 36²
256 + 1024 = 1296
1280 ≠ 1296
Answer:
I'm thinking it's 9
Step-by-step explanation:
The factor of the polynomial is (√5x - i√2)(√5x + i√2)(x + 4).
<h2>Polynomial</h2>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Given
5x³ + 20x³ + 2x +8 is a polynomial.
<h3>To find </h3>
The factor of the polynomial.
<h3>How to find the factor of the polynomial?</h3>
5x³ + 20x³ + 2x +8 is a polynomial.
Take common, we get
5x²(x + 4) + 2(x + 4)
(5x² + 2) (x + 4)
[(x√5)² - (i√2)](x + 4)
(√5x - i√2)(√5x + i√2)(x + 4)
Thus, the factor of the polynomial is (√5x - i√2)(√5x + i√2)(x + 4).
