A giant sequoia (scientific name: Sequoiadendron giganteum) is exactly as its name suggests- giant! Currently, the "General Sherman" tree, thought to be one of the largest giant sequoias in the world, resides in the Sequoia National Park, which is located in northern California. The tree's largest circumference, located near the base of the trunk, measures approximately 102.6 feet! Use scientific notation to represent the circumference of the General Sherman's trunk in inches. Include all of your calculations in your final answer.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
