Answer:
A
Step-by-step explanation:
I took it
The circumference is 22
Circumference = 2πr
22 = 2πr
It's the same thing as π*diameter
22 = <span>πd
divide both sides by </span><span>π to isolate d
d, or the diameter, equals 7.0028175 cm, or approx. 7 cm
the radius is half of the diameter so it is </span><span>3.50140875, or approx. 3.5 cm
the area of the circle is
</span><span>A = π r²
A = </span>π (3.5)<span>²
A = </span><span>π (12.25)
A = 38.4845
The area equals approximately 38.5 cm^2.
Hope this helps!</span>
Answer:
3
Step-by-step explanation:
25 ÷ 7 = 3.5
Because it wants complete sets you just put 3
<span>Given: 4y =2x-10, and y=6
Substituting for y in the equation gives 4(6) = 2x-10 or 24 = 2x-10
Adding 10 to both sides of the equation 24+10 = 2x - 10+10
34 = 2x
Dividing both sides by 2 34/2 = 2x/2
Answer 17 = x</span>
