The formula of a circumference is:

C=2\pi r

r - radius

or

C=d\pi

d - diameter

We have d = 12cm. Substitute:

C=12\pi\ cm

One-fourth of the circumference:

\dfrac{1}{4}C=\dfrac{1}{4}\cdot12\pi=3\pi\ cm\approx3\cdot3.14=9.42\ cm

<h3>Answer:  9.42 cm.</h3>

Jimmy borrowed $450 to start a lawn-mowing business. He charges $35 per lawn and it costs him $8 in operating costs per lawn.
Akimi4 [234]

Answer: $450

Step-by-step explanation:

Given that:

Amount borrowed = $450

Amount charged per lawn = $35

Operating cost per lawn = $8

Jimmy's cost (C(x)) :

Amount borrowed + operating cost

If x lawns are mowed :

$450 + $8 per lawn

$450 + $8x

C(x) = 450 + 8x

Intercept (value of y when x = 0

Value of C(x) ; when x = 0

C(x) = 450 + 8(0)

C(x) = 450 + 0

C(x) = 450

Please someone explain me why the answer is not B (4k2m3)?
Zigmanuir [339]

Hi there!

4k^2m^3 is definitely a factor of the the given terms. However, 4 is not the <em>greatest</em> common factor between 8 and 48; it is 8. Therefore, the GCF of the given terms would instead be 8k^2m^3.

I hope this helps!

A midsegment connecting two sides of a triangle is parallel to the third side and equal to which
lys-0071 [83]

Answer:

One half (1/2) the measurement of the third side

Step-by-step explanation:

Mid segment theorem defines the relationship between the constructed line joining the midpoint of two sides of a triangle, and parallel to the third side of the triangle which is also called the midsegment

Whereby the angles are defined by the proportion of the sides, the midsegment will have a length which is half the measurement of the length of the third side.
