Exact Area = 98pi
Approximate Area = 307.8760800518 (use calculator stored version of pi)
Approximate Area = 307.72 (using pi = 3.14)
Units are in square millimeters
======================================================
Explanation:
In 60 seconds, the hand sweeps out a full circle of radius 14. The area of this circle is
A = pi*r^2 = pi*14^2 = 196pi
Half of this is what the hand sweeps out in 30 seconds, so A/2 = (196pi)/2 = 98pi is the exact area it sweeps out. Your calculator would then show 98pi = 307.8760800518 approximately
If instead you use pi = 3.14, then the approximate area is 98*3.14 = 307.72
Answer:
-(2)x+2
Step-by-step explanation:
g(x)=F(x)+2
g(x)=-(2)x+2
2•3=9 2•2=4 2•2=4 9+4+4=17 the answer is 17
Answer:
y = 
x + 7
Step-by-step explanation:
Given
x = 3t ( divide both sides by 3 )
x = t
Substitute this value into y = 2t + 7
y = 2 × x + 7 = x + 7
