Answer:
B
Step-by-step explanation:
sin(theta) = sqrt(1-cos^2(theta)
sin(theta)=sqrt(1-1/2)=sqrt(1/2)=sqrt(2)/2 but as theta is in IV quadrant, sin(theta) will be negative
Just divide the number of centimeters by 100 and you will get the meters
Answer:
The area is 16.62
Step-by-step explanation:
The expression you use is pi x r squared. which is 3.14 x 2.3 x 2
2x + 4 = 3(x - 2) + 1
2x + 4 = 3x - 6 + 1
2x + 4 = 3x - 5
9 = x
So x = 9
