Answer:
First answer.
Step-by-step explanation:
This is called the Arc length, here is the formula:
Arc length = (angle/360)*(2Pi*radius)
So,
(45/360)*(2*3.14*4)
= 3.14
SO Pi !!!!!

Answer:
D. 187 m²
Step-by-step explanation:
Alrighty, so this is a standard area problem, the formula for finding the area of a triangle is base x height ÷ 2 so:
34 x 11 ÷ 2 = 187
So the area of the triangle is 187 m²
