Find the area of the figure. Round your answer to the nearest hundredth.

≈ 84.14 ft²

Step-by-step explanation:

The figure is composed of a rectangle and a semicircle, so

A = area of rectangle + area of semicircle

   = lb + πr²

diameter of circle = 14 - (4 + 4) = 14 - 8 = 6 , then radius r = 3

A = (14 × 5) + (0.5 × π × 3² )

   = 70 + 4.5π

   ≈ 84.14 ft² ( to the nearest hundredth )

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
