A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4 °F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5°F. Assume that sea level is at 0 feet of elevation. Find the submarine initial elevation as a rational number.

At the elevation of ft the below sea level of temperature water was °F

Step-by-step explanation:

Given Information.

ft. below sea level = °F

Submarine drops ft deeper so the temperature drops by ° F

We're looking submarine initial elevation.

Find the elevation the Submarine dove.

ft.

Now find the temperature.

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
