Area and circumference of this circle

Mathematics
1 answer:
faust18 [17]2 years ago
5 0

Answer:

Step-by-step explanation:

Given: The radius is 6 cm

To find the area + circumference we need to use 2 formulas:

Area: pi* radius^2

Circumference: 2*pi*r

First we can do the area

I will use "pi" for pi instead of 3.14

pi * 6^2

= 36 pi

The area is 36 pi

Next, circumference

2 * pi *r

2*pi*6

= 12 pi

So the area is 36 pi, and the circumference is 12 pi

A single yard is equal to 3 feet. So one yard 1 foot and 9 inches is:

3(10)+1 and 9 inches.

each feet has 12 inches, so it goes something like this:

12(31)+9 inches

multiply it out:

372+9\\381

Thats the total number of inches, now we divide by 3 (use long division:

\frac{381}{3}=127

Hope this helps!

Holly rode her bike for 24 miles at 6 miles per hour. She finished her ride at 1:00 p.m.
Bezzdna [24]
Time = distance/speed
Since you want to find the time Holly spent riding, you need to divide her distance (24 miles) by her speed (6 miles/hour) to get the number of hours (4) that she rode. Her starting time added to the time spend riding will give her ending time. One must subtract the riding time from the ending time to find the starting time.

Selection A is appropriate.
