Aswimming pool has a diameter of 32 feet. what is the area of a tarp needed to cover the swimming pool completely? use 3.14 to approximate for π . enter your answer, as a decimal rounded to the nearest tenth

A pool is circular shaped, so we need to use the area for a circle formula.

Radius= 1/2(Diameter)= 1/2(32)= 16

AREA CIRCLE FORMULA
A= πr^2

A= (3.14)(16)^2
square 16; multiply 16 by 16 one time

A= (3.14)(256)

A= 803.84 square feet

ANSWER: The area of the tarp needed, rounded to the nearest tenth, is 803.8 square feet.

Hope this helps! :)

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
