Hi there, first post on these forums. So i require assistance for a couple of word problems and would greatly appreciate the help.
A wheel is spinning at a rate of 220 rad/sec. Find the linear speed of a point on the rim, if the wheel's diameter is 1.5 meters.
For a circle of radius 30 meters, find the area (to the nearest m^2) of a sector with a central angle of 120degrees.
A flower garden is a 270degree sector with a radius of 4 meters. Find the exact area of the garden (in terms of pi), and approximate to 1 decimal place.
Thank you all in advance!
