I need a picture so I can under Stand how it's supposed to look
Answer:
The radius is 5 in
Step-by-step explanation:
The area of a circle is given by the formula
A = pi *r^2
We know the area = 78.5 in^2 (volume would be in^3 area is in^2)
78.5 = 3.14*r^2
Divide each side by 3.14
78.5/3.14 = 3.14/3.14*r^2
25 = r^2
Take the square root of each side
sqrt(25) sqrt(r^2)
5 =r
Answer:
Perry's claim is correct while Karina is incorrect
Step-by-step explanation:
Question is incomplete (See Attachment)
First, we need to determine the area covered by Karina and Perry
For Karina, there are 9 square boxes each of which has an area of 1 unit sq
So:
For Perry:
There are 18 square boxes, each of which has an area of 1 unit sq.
So:
Comparing both areas, we can conclude that <em>Perry's claim is correct while Karina is incorrect</em>
