Question

Find the circumference and the area of a circle with diameter 8 yd.

Use the value 3.14 for, and do not round your answers.


I need the area and circumference!!

Answer 1

25.12 and 50.24

Explanation:

8/2=4

4= radius

8= diameter

3.14*8=25.12

This would be the circumfrence (25.12)

3.14*4^2

3.14*16

50.24

This would be the area (50.24)

Hope this helps!

Answer 2

Answers:

area = 50.24 square yards

circumference = 25.12 yards

values are approximate

================================================

Work Shown:

d = 8 is the diameter

r = 4 is the radius, half the diameter

pi = 3.14 approximately

C = 2*pi*r = circumference

C = 2*3.14*4

C = 25.12 yards is the circumference. The circumference is the distance around the circle, aka the perimeter

An alternative formula you can use is C = pi*d

-------------------

A = area of circle

A = pi*r^2

A = 3.14*4^2

A = 50.24 square yards is the area
