Answer:
the answer is D) X _> 3
Step-by-step explanation:
Answer: Given radius (R) = 50
Diameter = 2R = 100
Circumference = 2πR
= 100π
= 314.15926535898
Area = πR2
= 2500π
= 7853.9816339745
Answer: 12
Step-by-step explanation:
this is a right angled triangle so you use the pythagorean theory
which is a^2 + b^2 = c^2
you have c and b already. c is the hypotenuse.
a^2 + 16^2 = 20^2
a^2 + 256 = 400
a^2 = 400 - 256
a^2 = 144
then you square root 144 and get..
a = 12
Add 't' to both sides. t+r=s
