Answer:
100π
Step-by-step explanation:
Area of a circle formula: πr²
The radius would be half of 20 m
So the radius, r is 10 m
Plug that in
πr²=π·10²=100π
b) f (-1) ese es el resultado
a+3
You cannot go any further in answering this question. These two terms are not like terms so they cannot be combined. Therefore, the answer is just a+3 itself.
y=17/2 y=5/2
