Answer:
22π=2πr. Divide both sides by 2π so r=11. Area = πr^2=121π.
Step-by-step explanation:
The height of the all after 2 secs is 86 feet
<h3>Functions and vales</h3>
Given the height in feet above the ground was given by the following function h(t) = -16t^2 + 75t
where:
t is the number of seconds since the ball was punted.
If the value of t = 2s, hence;
h(t) = -16t^2 + 75t
h(2) = -16(2)^2 + 75(2)
h(2) = -64 + 150
h(2) = 86
Hence the height of the all after 2 secs is 86 feet

The GCF stands for greatest common factor. To represent a sum by its GCF we need to use the distributive property and we need to first find the GCF of the numbers. Let's break each number by its factors:
We now multiply the numbers that appear on both.
We now apply the distributive property:
20% of 65 = 65 * 1/5, which is 13. so 20% of 65 is $13. so a discount of 20% = 65-13 which is $52
