Answer:
452.4 ft
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = 2πr . . . where r is the radius
Filling in the given number, we find the circumference to be ...
C = 2π(72 ft) = 144π ft ≈ 452.4 ft
The distance around the outside edge is about 452.4 feet.
Answer:
20
Step-by-step explanation:
To find Hypotenuse: Pythagorean Theroem
a^2+ b^2= c^2
The legs are A and B
The side that is directly across from the Right angle is C
12^2 + 16^2 =C^2
144+256=400
400 = c^2
Square root on both sides to get rid of c^2
The square root of 400 is 20
c=20
Write an equation of the direct variation that includes the given point (-8, -4)
Direct variation is y= kx for some constant k
Find k using the point (-8,-4)
y=kx
(-4)=k(-8) substitution
-4/-8=k(-8/-8) division property
1/2=k
equation of direct variation is y=1/2k
Yes, it does! evaluating and solving an expression are the same thing!
