7b / 12 = 4.2
multiply both sides by 12
7b = 50.4
divide both sides by 7 to isolate b
b = 7.2
Answer:
and 
Step-by-step explanation:
The question is incomplete as the attachment to solve segment DE is missing. However, see attached for complete question.
Given
Required
Find x
Length of DE
To find x, we need to first simplify the given equation
Multiply both sides by 
Subtract 15 from both sides
Divide both sides by 10
From the attached;
Substitute 6.6 for x
Hence and
The answer I think should be right would be 3.
It’s odd because you need to round it. But anyway I hope this helped. Rate my answer if I was wrong or correct
Circumference of a Circle,C=2πr
π=3.14
r= of the circle
Area of the circle= πr²
We know that
Area= 49 π²
πr²=49
r²=49/π
=49/3.14
=15.60
r= √15.60
=3.9 units
Circumference of a Circle,C=2πr
=2*3.14*3.9
=24.492 units
