Kaia throws a stone vertically upward from a bridge. The height, in meters, of the stone above the water at time t can be modeled by the quadratic function:
h(t)
--4.9t2 + 9.8t + 39.2
After how many seconds does the stone hit the water?

answer: 7

step-by-step explanation:

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
