Find the area of the region inside the curve r=3sintheta and outside the curve r=root3costheta

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

It’s hard to understand what you put.. can you show a picture ?

Dwould be the answer

Iam not sure , but probably 750 or 7.5
