Find the circumference and the area of a circle with diameter 4 ft.

Mathematics
1 answer:
ICE Princess25 [194]3 years ago
6 0

Answer:

To find the circumference of a circle, your equation is 2*pi*radius

C=2*3.14*2 (radius is half of diameter so 4/2=2, 2=radius)

C=12.56 ft

To find the area of a circle, your equation would be pie*r^2

A=3.14*2^2

A=3.14*4

A=12.56 sq. ft

Hope this helps ;)

Raul plans to run 30 miles this week. He wants to run the same number of miles each day of the week. He says he will run 7/30 mi
dmitriy555 [2]
No, because if he runs 7/30 mile each day he will run 210 miles each week because he is running 30 miles every day so he has to run 7/4.28 miles each day of the week to get 30 miles each week.
