Afamily from switzerland is visiting the united states. their first stop is a bank, where the following exchange rate is posted; usd to chf=0.89. on this day how many u. s. dollars will the family get for each of their swiss francs? round tot he nearest cent. a: $0.11 b: $0.89 c: $1.12 d: $1.89

1/0.89= 1.12 
So, I think the answer is C. 1.12
But in today's world, 1 USD is equal to 1 Swiss Franc...why don't you ask your teacher...I am doubting myself!

See diagram.we use washers to get the area and we will be integrating with respect to xouter radius is the  distance between y = e^x and y = -1    inner radius of washer is the distance between y = 1 and y = -1    the area of one cross-section of a washer is    solid lies between x = 0 and x = 2. the volume is    if you need this expanded, then    the question doesn't say to evaluate, so we're done.
