Answer:
6.3feet
Step-by-step explanation:
Given data
Radius= 4feet
The expression for the circumference of a circle is
C= 2πr
Substitute
C=2*3.142*4
C=25.136 feet
Also, a 90° arc is 1/4 of the circumference of a circle
Hence the length of the 90° arc is
=25.136/4
=6.284 feet
=6.3feet
um half hour? because at 4mph youll get 4 miles in an hour so 2 miles, is half the rate which makes it half hour
X=2
You add 3x and 4x which is 7x then divide 14 by 7 which is 2
Answer:
B is (7,-4) C is (7,-2) D is (5,0)
