A circular oil spill continues to increase in size. The radius of the oil spillin miles, is given by the function r(t) = 0.5 + 2t , where is the time in hours . The area of the circular region is given by the function A(r) = m ^ 2 where r is the radius of the Circle at time Explain how to write a composite function to find the area of the region at time t

Step-by-step explanation:

r(t) = 0.5 + 2t

A(r) = πr²

= π(0.5 +2t)² or

A(t) = π (0.25 +2t +4t²)

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.

160 cm

step-by-step explanation:

you have to add all the sides together
