Answer:
Two isosceles right triangles. and
Step-by-step explanation:
The length of one side is:
An isosceles right has two sides of identical length, which are both legs and perpendicular to each other. There are two possibilities:
Answer:
a = 254.5 mm² ( if using accurate value of π)
a = 254.4 mm² (if using 3.14 as approximate value of π)
Step-by-step explanation:
a = πr²
a = π * 9²
a = π * 81
(note using π = 3.1415926536)
a = 254.4690049408
Rounded
a = 254.5 mm²
(a = 254.4 If using π = 3.14)
Answer:
If f(x) = 3x, this means that any number that replaces x in the parenthesis, would replace x in the right side too.
When x = -1:
f(-1) = 3(-1) = -3
When x = 0:
f(0) = 3(0) = 0
When x = 3:
f(3) = 3(3) = 9
