Answer:
3.14
Step-by-step explanation:
Area of a corcle is sexpressed as';
A = πr²
π = A/r²
π = 78.54/5²
π = 78.54/25
π = 3.1416
When the area is divided by radius the required constant is 3.14
Answer:
Slope, m = 5
Step-by-step explanation:
Picking points on the x-axis and y-axis of the graph;
Point on x-axis (x1, x2) = 2, 4
Points on the y-axis (y1, y2) = 10, 20
To find the slope;
Mathematically, slope is given by the formula;
Substituting into the equation, we have;
Slope, m = 5
factor 9 out of the equation
18x^6 / 27x^4 becomes
2x^6 / 3x^4
cancel out common factors to get
2x^2/3
a) C = 40 + 30t
b) 280 = 40 + 30t
30t = 240
t = 8
