the formulae for finding the surface area of a sphere os given by A=4 pi Rsquared. calculate the radius of the sphere whose surface area is 616cm2. take pi 22/7
please help me...​

Answers

Answer 1

Answer: 7cm

Explanation:

The surface area of a sphere is calculated by using the formula:

A = 4πr²

Since the surface area is 616cm², using the formula given, the radius will be calculated thus:

A = 4πr²

616 = 4 × 22/7 × r²

616 = 88/7 × r²

Multiply both side by 7/88

616 × 7/88 = 88/7 × 7/88 × r²

49 = r²

r = ✓49

r = 7

The radius is 7cm

How does the Sun's energy drive convection in the Earth's atmosphere? The Response area's energy warms the land and Response area on Earth. As they heat up, the Response area above them becomes warmer and Response area dense and begins to Response area. Near the top of the atmosphere, the air cools down and becomes Response area dense and begins to Response area, creating a circular motion. How does the Sun's energy drive convection in the Earth's oceans? The Sun's energy warms the oceans on Earth. The warm water moves towards the Response area and the colder water moves towards the Response area , creating a circular motion.

Answers

Answer:Convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid.

Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere. As it rises, the bubble cools with the heat contained in the bubble moving into the atmosphere.As the hot air mass rises, the air is replaced by the surrounding cooler, more dense air, what we feel as wind. These movements of air masses can be small in a certain region, such as local cumulus clouds, or large cycles in the troposphere, covering large sections of the earth. Convection currents are responsible for many weather patterns in the troposphere.

Explanation: The Transfer of Heat Energy

The heat source for our planet is the sun. Energy from the sun is transferred through space and through the earth's atmosphere to the earth's surface. Since this energy warms the earth's surface and atmosphere, some of it is or becomes heat energy. There are three ways heat is transferred into and through the atmosphere:

the rate at which a person uses energy when the body is at rest

Answers

Answer: Basal metabolic rate (BMR)

Explanation: BMR is the number of calories required to keep your body functioning at rest. BMR is also known as your body's metabolism; therefore, any increase to your metabolic weight, such as exercise, will increase your BMR.

The rate at which a person uses energy when the body is at rest is known as Basal metabolic rate (BMR).

What is the Basal metabolic rate?

The basal metabolic rate may be defined as the rate at which energy expenditure is carried out by the body of an individual at rest. In a more simple sense, it is described as the amount of energy that your body needs to accomplish its most basic (basal) life-sustaining functions properly under normal conditions.

According to the context of this question, it governs all the cellular and metabolic activities of the cells very precisely in order to make organisms identical for their survival.

The various level of BMR reveals the actual condition of the body. An average male has a BMR of around 7100 KJ/day. While in the case of females, it is generally lower.

Therefore, the basal metabolic rate (BMR) is the rate at which a person uses energy when the body is at rest.
