We know that
<span>the sphere is divided into two hemispheres
</span><span>the two hemispheres are equals
</span><span>
if </span><span>Tran computes the amount of paint needed to cover the sphere
</span><span>therefore
</span>Tran computes the amount of paint needed to cover <span>both hemispheres.
</span>
the answer is
Tran found the minimum amount of paint needed to cover both hemispheres.
[surface area of sphere]=4*pi*r²
[surface area of each hemisphere]=2*pi*r²
circumference=18.84 cm------> 2*pi*r------> r=18.84/(2*pi)------> 3cm
[surface area of each hemisphere]=2*pi*3²---------> 56.52 cm²
surface area of sphere=2*56.52=113.04 cm²
X+4y+x+y= 4x+y=180
simplify by adding like terms
2x+5y= 4x+y=180
Subtract y from each side
2x+4y=4x=180
Subtract 2x from each side
4y=2x=180
y=180/4=45
x=180/2=90
14/16 divided by 2 is 7/8 or D.
Hey there,
When finding the largest prime factor of a number, basically all you doing is find the divisible of the number. For example:
What are the prime factors of 8?
8
/ \
4 2
/ \ \
2 2 2
Hope that helps.
