-16/-2
Divide numerator & denominator by 2
-8/-1 = 8
They are both parallelograms because the sides are parallel to one another
Answer:
arc length =11
Step-by-step explanation:
To find the arc length , we take pi *2 r and multiply by the fraction of the circle
The circumference is 12 which is equal to 2 * pi *r
arc length = 12 * 330/360
arc length = 12 * 11/12
arc length =11
Answer:
The Surface area of the moon is 
Step-by-step explanation:
Given:
Diameter of the moon = 3.8 x 10 to the 8th
To Find :
The surface area of the moon = ?
Solution:
The moon is in the shape of of the sphere .
So the surface area of the moon = surface area of the sphere
The surface area of the sphere = 
Where r is the radius of the sphere
Radius , r = 
r = 
r = 
Now the surface area of the moon with radius r =
is
=> 
=>
=>
=>
=>
Answer:
Hello! answer: 20
Step-by-step explanation:
circumference is just diameter × pi so If we do circumference ÷ pi we will get our diameter so
125.6 ÷ 3.14 = 40 But remember diameter is just twice the radius so all we have to do is divide by 2 to get our radius so
40 ÷ 2 = 20 So 20 is the radius Hope this helps!
