The center circle on a playing field has a radius of 7.5m find its circumference

Nady [450]

<h3>Given:</h3>

r= 7.5 m

r= radius

The circumference of the circular playing field.

<h3>Solution:</h3>

$\huge\boxed{Formula:C= 2\pi{r}}$

We'll have to multiply 2, π and radius.

Substitute the values according to the formula.

$C= 2× \pi ×7.5$

$C= 47.12389$

$\large\boxed{C= 47.12 \: m}$

Therefore, the circumference of the circular playing field is 47.12 feets.

Please help me b minus 3/4 = 7/10

RoseWind [281]

B - 3/4 = 7/10
add 3/4 to both sides to isolate the b
b = 7/10 + 3/4
b = 28/40 + 30/40
b = 58/40
b = 1 18/40
b = 1 9/20
