A landing pad for a helicopter is in the shape of a circle with a radius of 7 meters. Which of the following is closest to the area of the landing pad?
Accepted Solution
A:
Answer:The approximate value of the area is [tex]153.86\ m^{2}[/tex]Step-by-step explanation:we know thatThe area of the circle (landing pad) is equal to[tex]A=\pi r^{2}[/tex]we have[tex]r=7\ m[/tex]substitute[tex]A=\pi (7)^{2}[/tex][tex]A=49\pi\ m^{2}[/tex] ----> exact value of the areaFind the approximate valueassume [tex]\pi=3.14[/tex][tex]A=49(3.14)=153.86\ m^{2}[/tex] ------> approximate value of the area
