You have to use the Pythagorean theorem a squared plus b squared is c squared so 13 squared plus 18 squared equals c squared. 13x13=169 18x18=324 169+324=493 so c squared is 493 to get c you square root 493 which equals 22.2 so the diagonal, c, is 22.2 centimeters long

The spinner is divided into eight equal sections marked with eight different colors what situation could be represented by the s
meriva
I believe the answer you looking for is Probability.

This means that if someone spinned that wheel, they have a probability of getting the color they need.

For instance,
Let's say this wheel had the colors red, orange, yellow, green, blue, indigo, purple, and pink.
If I wanted the color red on the spinner, I have a 1/8 chance to spin the color red. I have a 7/8 chance of NOT spinning red. However, let's say the wheel had 4 colors that were pink and 4 colors that were blue. If I wanted to spin the color pink, I would have a 4/8 chance OF spinning it and a 4/8 chance of NOT spinning it. 4/8 is also equivilant to 1/2.

I hope this helps you understand!!
Please mark brainliest!!
Thanks!!

A gardener makes a new circular flower bed. The bed is teen feet in diameter. Calculate the circumference and the area of the ci
KATRIN_1 [288]

Answer:

I. Circumference of circular flower bed = 31.42 ft.

II. Area of circular flower bed = 78.55 ft²

Step-by-step explanation:

Given the following data;

Diameter = 10 ft

Radius = diameter/2

Radius = 10/2

Radius, r = 5 ft

I. To find the circumference of the circular flower bed;

Circumference of circle = 2πr

Substituting into the formula, we have

Circumference of circular flower bed = 2*3.142*5

Circumference of circular flower bed = 31.42 ft

II. To find the area;

Area of circle = πr²

Substituting into the formula, we have;

Area of circular flower bed = 3.142*5²

Area of circular flower bed = 3.142*25

Area of circular flower bed = 78.55 ft²
