Answer:
G, 113.04
Step-by-step explanation:
To find the area of the head of the nail you need to use the*
> A= π*r^2* A equals area, π equals pi(3.14) and then you square your raidius, which is 6 in your case.
π*r^2
plug in your six as the *r
π*6*^2
solve 6^2=36 and multiply that by your π which is 3.14
3.14*36
=113.04
Hope that helped!! :)
Y and x are directly proportional, as stated by hypothesis. Let's use the rule of three to find y when x = 8.
x=5 --> y=12
x=8 --> y=?
? = (8*12)/5 = 96/5 = 19.2
So y directly varies with x, and y=12 when x = 5, then y=19.2 when x=8.
Hope this Helps! :D

The side length of the square concrete slab if the area is increased by 25% is 5feet
The formula for calculating the area of a square is expressed as:
A = L² where:
L is the side length of the square
Given the area of the square concrete slab = 20 square feet
20 = L²
L =√20
If the area is increased by 25%, new area will be:
An = 20 + (0.25*20)
An = 20 + 5
An = 25 sq.ft
Get the new length
An = Ln²
25 = Ln²
Ln = √25
Ln = 5feet
Hence the side length of the square concrete slab if the area is increased by 25% is 5feet

10x10x10x10, you have to multiply 10 by 10 four times, since it's 10 to the power of 4.
