Find the circumference and area of a circle with a diameter of 14 inches. Leave your answers in terms of pi.
IRINA_888 [86]

Step-by-step explanation:

step 1. The circumference (c) of a circle is the diameter of a circle x pi. c = d(pi) = 14pi.

step 2. The area (A) of a circle is the radius of a circle squared x pi. The radius of a circle is 1/2 x the diameter. A = (14/2)^2(pi) = 49pi.

Pls help me help me help me​
Ganezh [65]

Answer:

C. -3/2

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

We know that line <em>m </em>is perpendicular to line <em>l. </em>

Line <em>l </em>has a slope of 2/3. To find the slope of line <em>m, </em>find the negative reciprocal of 2/3.

Negative: switch the sign

2/3 --> -2/3

Reciprocal: switch the numerator (top number) and denominator (bottom number)

-2/3 --> -3/2

Line <em>m</em> has a slope of -3/2 and C is correct.
