Arianna is designing a square table. The top of the table is made of wood with a circular glass center as shown.
Radius 1.4.
4ft edge of square table.
Part A. What is the area of the glass center in Arianna's table rounded to the nearest tenth
of a square foot? Use 3.14 for 1.
Part B. What is the area of the wooden part of the table rounded to the nearest tenth of a
square foot?

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?
