Nina can ride her bike 63,360 feet in 3,400 seconds, and Sophia can ride her bike 10 miles in 1 hour . What is Nina’s rate miles

faltersainse [42]

Answer:

Nina's rate in miles per hour is 2.7 miles/hour

Nina bikes faster

Step-by-step explanation:

we know that

1 hour=3,600 seconds

1 mile=5,280 feet

Convert feet to miles

63,360 feet=63,360/5,280=12 miles

Convert seconds to hours

3,400 sec=3,400/3,600=0.94 hours

Find Nina's rate in miles per hour

12/0.94=12.7 miles/hour

Sophia's rate in miles per hour is 10 miles/hour

Compare the rates

12.7 miles/hour > 10 miles/hour

therefore

Nina bikes faster

The radius of a circle is 16 millimeters. What is the circle's area?

Kisachek [45]

Answer:

803.84 millimeters²

Step-by-step explanation:

How do we find the area of a circle?

The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.

Solving

$3.14 *16^2$
$3.14*256$
$803.84$

Therefore, the area is 803.84 square millimeters.

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.
