Answer:
Circle B
3.14 cm
Step-by-step explanation:
1. The diameter is twice the radius, so the diameter of Circle B is ...
2 × 5 cm = 10 cm
This diameter is greater than the 9 cm diameter of Circle A, so Circle B is larger and will have a larger circumference.
2. The circumference is the product of π and the diameter. Then the difference between the two circumferences is ...
... (circle B circumference) - (circle A circumference) = π·(10 cm) - π·(9 cm)
... = π·(10 -9) cm = π·1 cm ≈ 3.14 cm
Answer:
14, 15, 16
Step-by-step explanation:
45-2 <em>The difference in integers, that way they're all the same number</em>
43/3=14
14, 15, 16
x2=36
We move all terms to the left:
x2-(36)=0
We add all the numbers together, and all the variables
x^2-36=0
a = 1; b = 0; c = -36;
Δ = b2-4ac
Δ = 02-4·1·(-36)
Δ = 144
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ‾‾√=144‾‾‾‾√=12
x1=−b−Δ√2a=−(0)−122∗1=−122=−6
x2=−b+Δ√2a=−(0)+122∗1=122=6
