An impact crater left by an asteroid strike has a radius of 85 km What is the area of the crater?

The formula for area of a circle is a = πr2. If the radius is 85km, the area would be approximately 22686.5 km2.

What would happen if a 1 kilometer wide asteroid hit the Earth?
Depending on where it hits, it might be anywhere from very damaging to catastrophic. If it were to strike in a sparsely inhabited area like Siberia or the Australian "Outback", it would likely cause very serious damage to everything within about a 300 KM radius, dig a substantial crater, and scatter ejecta over a radius of 400 km or more. If it were to strike a populous area like India, Europe or the Americas, the death toll could be in the hundred-million plus range. A water impact might cause a tsunami capable of inundating all the surrounding coastlines. An asteroid impact in the Indian Ocean about 4000 years ago may have caused a tsunami throughout the Indian Ocean basin, giving rise to the near-universal legends about a great flood; Noah and the Ark, and the Sumerian Gilgamesh epics, for example. And there are apparently Australian Aboriginal "Dreamtime" legends recounting a flood. See the link below for the Impact Effects Calculator to figure out what might happen if an asteroid were to strike the Earth.
How many people are killed in the past from asteroid?
The last massive asteroid strike on earth was before human beings existed, making the answer "none".
What countries are hit by asteroid?
Asteroids, if large enough, can strike anywhere on the Earth.
What are two variables that could cause meteorites to form different sized craters?
There are a number of factors that determine the size and shape of a crater. The two most significant are the mass of the impactor, and the speed. Other influential factors would include the composition of the object (solid rock or more aggregate, like pebbles? Ice?) the shape of the object, and the composition of the impact site. If it is on dry land, it will be more likely to leave a visible crater, while a water or marshy impact site would be quickly erased. If a water impact, the depth of the water and the topography of the surrounding seas would be vastly important. A strike in a deep ocean basin might be relatively mild, while a water strike in the South China Sea or Gulf of Mexico, with the constricted water flow, might result in catastrophic tsunamis inundating the surrounding areas.
What is the name of the asteroid that will be near earth in 2029?
99942 Apophis is an asteroid where initial observations indicated a small probability (up to 2.7%) that it would strike the Earth in 2029.Later observations concluded that the asteroid would miss the Earth.The chances are now set at a one in 3 million that it will hit Earth.
What is an asteroid strike?
Barringer or Meteor Crater Arizona is a good example
When meteorites or other objects strike the Moon what do they create?
Impact Basin / Impact Crater
What state in Mexico did the meteor Chicxulub strike?
The Chicxulub crater is the area in the state of Yucatan that was hit by an asteroid. It is about 66 million years old.
Why is the earth's surface not covered with crater?
Weathering and erosion tend to level out crater features, whether impact or volcanic, over time. The atmosphere also protects the surface from many meteor impact events, by burning them up before they strike.

What kind of feature might be formed on Earth if a large meteorite reached its surface?
A large meteor strike on the earth might cause a crateron the surface. If it struck the water, it may leave a bit of a crater in the sea floor, depending on the size and velocity and composition of the meteor and the depth of the sea where it impacted. If it hit land, there'd be a big "dent" in the ground where the missle and the blast of impact gouged it out.

Can a asteroid damage a planet?
An asteroid can indeed damage a planet when it strikes it. It is possible that an asteroid strike resulted in the dying off of the dinosaurs on Earth. There are certainly some large craters on Earth that are suggestive of asteroid strikes.
When a crater formed in Arizona why was it in Arizona?
Meteor Crater was formed by a meteor strike, not a guided missile from space. Call it a random act of nature.
Where did an asteroid strike earth 65 million years ago?
It struck in the Yucatan Peninsula in Mexico. This was actually a bad place to hit as it was a huge limestone plate. This launched huge piles of debris all around the world, multiplying the impact of the... uh... impact.
