What is the arc length of a circle that has an 8-inch radius and a central angle that is 95 degrees? Use 3.14 for π and round your answer to the nearest hundredth.

Answers

The arc length of a circle can calculated by the equation:

Arc length = 2πr(C / 360)

where r is the radius and C is the central angle.

Therefore, the arc length of this circle should be calculated as follows:

Arc length = 2π(8)(95 / 360)
Arc length = 13.26 in

From the calculations, we can see that the length of the arc is 13.3 inches.

What is the arc?

The arc is the portion of the circle that is bonded by two radii. Recall that the radius is a line drawn from the center to any part of the circumference.

Arc length = 2πr(C / 360)

Hence;

r = 2 * 3.14 * 8(95/360)

r = 13.3 inches

Process that takes place at mid-ocean ridgesA. Sea-floor spreading

B. Continental drift

C. Magnetic reversal

D. Magnetic minerals

E. Fossils

Answers

Answer;

-Sea-floor spreading

Sea floor spreading is process that takes place at mid-ocean ridges, evidence is found in magnetic minerals on the ocean floor.

Explanation;

-Seafloor spreading is a geologic process in which tectonic plates; large slabs of Earth's lithosphere; split apart from each other.

-Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle. Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense.
a. sea-floor spreading

The ocean and the atmosphere serve as long-term storage areas for carbon and other nutrients. What are these storage areas called?

Answers

The ocean and atmosphere this time where carbon is stored is called carbon sink. This is similar to the ocean also where it is called the largest heat sink since the surface area receives the direct heat of the sun. the answer is called carbon sink.
