Answer:

this might help

Step-by-step explanation:

Remember, to find the area of a circle, you need to multiply pi by the radius squared

The area, 'A', of the circle is 153.86 inches squared

'π' is pi, an irrational number with a value of approximately 3.14

'r' is the radius, which is what we are solving for here

We plugged our information into the A=πr2 formula

We get "r=7", which means the radius of the circle is 7 inches!

Answer: See explanation

Step-by-step explanation:

The dimensions of the first drawing will be 1/3 the dimensions of the leaf and the dimension of the oak leaf is 5 1/2 inches. Therefore, the dimensions of the 1st leaf:

= 1/3 × 5 1/2

= 1/3 × 11/2

= 11/6

= 1 5/6 inches

This is less than 5 1/2 inches

The dimensions of the second drawing will be 2 1/2 the dimensions of the leaf. This will be:

= 2 1/2 × 5 1/2

= 5/2 × 11/2

= 55/4

= 13 3/4 inches

Thus is greater than 5 1/2 inches

arsen [322]

Unit walking rate in miles per hour = 5 2/3 / 2 2/3 = 17/3 / 8/3 = 17/3 x 3/8 = 17/8 = 2 1/8 miles per hour.

Unit walking rate in hours per mile = 1/ 17/8 = 8/17 hours per mile.

If you travel south from the equator to 25°S, how far will you have to travel? The circumference of the earth is approximately 4

julsineya [31]

Answer:

2,777.8 km or 1,729.2 mi

Step-by-step explanation:

first think about how many degrees would you travel if you wanted to do a whole circunference always going south: it would take 360 degress to complete a circunference.

Then you can use a rule of three to find the answer:

If the whole circunference is 40,000km and in degrees is 360, then how much 25 degrees would be?

$x= \frac{25}{360}*40,000$

$x= 2777.8$
