What's is the area of circle of circle with a radius of 7 inches use =3.14.

To find the area of a circle you use pi x rsquared. So just 3.14x7^2= 153.86

Step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
