Answer:

31.4 m , 37.68m , 43,96in , 3.14 ,175.84 ft , 3.14 , 25 ft

Step-by-step explanation:

Circumference of circle(c)= 2πr or πd
a.
Given,
d=10m
Now,
C=πd
3.14*10
31.4 m
b.
Given,
r=6
Now,
C=2πr
2*3.14*6
37.68m
2.
Given,
d=14in
Now,
C=πd
3.14*14
43.96 in
I used 3.14 for value of π.
4. Given,
r=28ft
Now,
C=2πr
2*3.14*28
175.84 ft
I used 3.14 for the value of π.
5.
Given,
C=78.5 ft
Now,
C=πd
78.5/π=d
d=78.5/3.14
d=25 ft

A wire, 224 inches long, is cut into three pieces. The first is twice as long as the second.

iragen [17]

Answer:

64in

Step-by-step explanation:

first =2* second

second=2*third since the third is half of second

first =2*2*third=4*third

now lets put them all together

first+second+third=224

4*third+2*third+third=224

7*third=224 so the third part is 32

but we need the second piece

2*32=64
