2 answers:
Answer:
Circumference: 65.9734 inches
Area: 346.361 square inches
Step-by-step explanation:
If the diameter is 21 inches, we know the radius, r, is 10.5 inches because the radius measure is half of the diameter.
Circumference Formula: 2πr
=2π(10.5)
=65.9734 inches
Area formula: π
π(10.5)^2
= 346.361 square inches

Answer:
The equation of line parallel to given line passing through (6,7) is:
Step-by-step explanation:
Given equation of line is:
We have to convert the equation in slope-intercept form. The slope-intercept form is given by:
Adding 3y on both sides and subtracting 9 from both sides
Dividing whole equation by 3
Let m be the slope of given line then
m = 2/3
Let m1 be the slope of line parallel to given line. Slopes of two parallel lines is equal that means:
m = m1 = 2/3
The equation of line will be:
Putting the point (6,7) in equation
Putting the value of b
Hence,
The equation of line parallel to given line passing through (6,7) is:
