The diameter of a circle is 3 cm. Find the circumference to the nearest tenth.
nika2105 [10]

Answer:

The answer is 9.4 cm.

Step-by-step explanation:

To solve for the circumference of the circle, use the circumference formula, which is C = 2 \pi r.

Next, in the problem, the circle has a diameter measure but no radius measure. To find the radius of this circle, divide the diameter (3 cm) by 2, and it will equal 1.5 cm. The radius is being divided by 2 because the radius of any circle is equal to half the diameter of the circle.  

Then, plug in the information given from the problem into the formula, and the formula will look like C = (2) (\pi) (1.5 cm).

Finally, solve the equation, and the answer is 9.4 cm.

If Line l^1 has equation y = 11 - 3x Find the Equation of the Line through (5,3) parallel to l^1 So y = ??????
gregori [183]

Answer:

Step-by-step explanation:

Given equation of line is y = 11 - 3x

The equation takes the form of slope intercept equation ; y = mx + b where, m = slope and b = intercept.

Comparing the equation;

Slope, m = - 3

We obtain the equation of line passing through the point (5, 3) and parallel to the given line ;

y - y1 = m(x - x1)

x1 = 5 ; y1 = 3

y - 3 = - 3(x - 5)

y - 3 = - 3x + 15

y = - 3x + 15 + 3

y = - 3x + 18
