Find the circumference with the given radius.round to the nerest tenth.use 3.14 π r = 7cm

brilliants [131]

Answer:

44.0 cm.

Step-by-step explanation:

The formula for the circumference of a circle is

$C=2\pi r$

So we can substitute 7 for r and 3.14 for pi:

$C=2(3.14)(7)=43.96$ cm

And since we're rounding to the nearest tenth, the answer is 44.0 cm.

12/15 in simplest form

alex41 [277]

$\frac{12}{15}$ in simplest form:

First, find the greatest common factor (GCF) of 12, 15.
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 15: 1, 3, 5, 15
The GCF is 3.
Second, divide the numerator (12) by the GCF. / Your problem should look like: 12 ÷ 3 = 4
Third, divide the denominator (15) by the GCF. / Your problem should look like: 15 ÷ 3 = 5
Fourth, rewrite the fraction in the simplified form. / Your problem should look like: $\frac{4}{5}$

Answer: $\frac{4}{5}$
