A water fountain shoots up a jet of water. The water falls back down onto the ground in the shape of a circle. Michelle wants the circle of water on the ground to be 0.7 meters wider on each side. She gradually increases to 0.2 square meters per second. Use 22/7 as an approximation for π.
a) Find the area of the original circle of water
b)find the area of the larger circle of water
c) how long does it take for the original circle of water to become the larger circle of water? Round your answer to the nearest second.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
