A flying disc has a radius of 7 inches. What is the area of one side of the flying disc to the nearest square inch? Use 3.14 as an approximation for pi.
So the forumla for area of a circle is A= pi r^2.
So plug it in, A= 3.14(7^2), 3.14*49 = 153.86in^2
Hoped I helped!
To find the area of one side of the flying disc, we need to calculate the area of a circle. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.
In this case, the radius of the flying disc is 7 inches. To find the area, we can substitute the values into the formula:
A = 3.14 * (7 inches)^2
First, we square the radius: 7 inches * 7 inches = 49 square inches
Next, we multiply the squared radius by π (approximated as 3.14):
A = 3.14 * 49 square inches
A = 153.86 square inches
To the nearest square inch, the area of one side of the flying disc is 154 square inches.
just use the formula:
a = πr^2 = 49π = ...
A = pi * r^2
A = 3.14 * 49
A = ________ square inches
