The area of a circle is A=πR2 , as a function of time (in seconds) it is A(t)=π(Rt)2
Find the derivative of the area with respect to the radius
dA/dR=A'(t)=2πRt
So the rate the area is increasing at 7s is given by
A'(7)=2π(70X7)=980π cm/s2 or 3078.76 cm/s2
Waves transfer energy outward equally. Since there is no barrier to the water, when a raindrop hits the water that energy of the raindrop falling has to go somewhere, the energy is transferred from the raindrop to the water and goes outward from the epicenter (where the raindrop fell). The waves (circles) will continue to travel an equal distance unless there is an outside force such as wind, another object, ect. to stop the wave
I think you probably mean platonic. The cube is one of only five platonic solids. These are the only shapes that can be made with outward-pointing corners and sides all of the same lengths.
In terms of propositional calculus (logic), the converse of "if A then B" is "if B then A". The inverse is "if not A then not B". The converse and inverse are contra-positives of each other, and therefore logically equivalent. Answer 1 ======= In terms of optical lensing, converse lenses will be thicker in the center where inverse lenses will be thinner in the center. Converse bends outward. Inverse bends inward.
Ringworm is circular in shape because the fungus that causes it grows outward in a circular pattern on the skin, creating a ring-like appearance.
A fan is an example of circular motion because its blades rotate around a central axis, creating airflow in a circular pattern. As the blades spin, they push air outward in a circular motion, generating a breeze that is felt across the room.
A circular wave is a type of wave that spreads out from a central point in a circular pattern. It is often observed in water when a disturbance, such as a pebble being dropped, creates ripples that move outward in all directions. Circular waves exhibit characteristics like interference, diffraction, and reflection.
Circular waves refer to the pattern created on the surface of a liquid when an object is dropped or disturbed. These waves extend outward in a circular motion from the disturbance point, gradually dissipating as they move further away. This phenomenon is commonly observed in bodies of water like ponds or lakes.
Waves travel outward in a circular pattern away from the original disturbance because the energy from the disturbance spreads equally in all directions, causing wavefronts to propagate in a circular manner. This circular pattern allows the waves to spread outwards efficiently and maintain their intensity over distance.
Radio waves were discovered before the radio was invented.
Waves, such as water waves or electromagnetic waves, can give particles a circular motion when generated by energy traveling outward from the epicenter. This circular motion is a result of the energy causing the particles to oscillate in a circular path, transmitting the wave's energy through the medium.
a satellite in orbit; it is moving at constant speed but is accelerating outward in circular acceleration, balanced by gravity acceleration (centripetal force).
We have to use implicit differentiation, because we are figuring how it is changing with respect to time, not just the radius. So recall that the area of a circle is given by the formula A = â•¥r2. So....dA/dt = (â•¥)(2r) dr/dtWe need to calculate dA/dtAfter 2s, r = 50(2) = 100dA/dt = â•¥(2)(100)(50)= 10,000â•¥ cm2/s
It's called a brim.brim: a circular projection that sticks outward from the crown of a hat
Ringworm forms a ring shape on the skin because the fungus grows outward in a circular pattern, causing the center to heal while the edges continue to spread, creating the characteristic ring shape.
Craters are generally circular because impacts from space objects are perpendicular to the surface of the impacted body, creating a circular shock wave that radiates outward equally in all directions. This results in a symmetrical circular shape as the impact energy is dispersed uniformly.
