A boat uses two pontoons to float. Each pontoon consists of a cylinder with a hemisphere at each end, as shown. Find the total volume of the two pontoons. Round your answer to the nearest whole number.

Step-by-step explanation:

Let's find the volume of 1 pontoon first.

Volume of pontoon

= volume of cylinder + 1 sphere

(since there are 2 hemispheres in total)

Volume of cylinder=

Volume of sphere=

Radius= 1÷2

Radius= 0.5 ft

Volume of cylinder

Volume of sphere

Volume of 1 pontoon

Total volume of 2 pontoons

(nearest whole number)

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

so, converting firstly the mixed fractions to improper fractions and then "adding".
