The first option is correct
Answer:
36.6
Step-by-step explanation:
3k= 3*12.2
3*12.2=36.6
Answer:
Step-by-step explanation:
r and d are the radius and diameter of a, respectively.
area of a = πr² = 500 in²
r = √500/√π = 10√5/√π
d = 20√5/√π
radius of b = 3r = 30√5/√π
area of b = π(30√5/√π)² = π(4500/π) = 4500 in²
Equation of the line is y = 4x + 4
Step-by-step explanation:
- Step 1: Given that the line passes through (2,4) and (1,0). Equation in slope-intercept form is y = mx + b
- Step 2: Find slope, m using the formula m = (y2 - y1)/(x2 - x1)
⇒ m = (0 - 4)/(1 - 2) = -4/-1 = 4
- Step 3: Find the y-intercept.
⇒ b = 4
- Step 3: Substitute the values in the equation
⇒ y = 4x + 4
