Parentheses aren't needed but:
(Also "•" means multiplying)
(3 - 5) • x
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
Answer:
x = 47
Step-by-step explanation:
KY + YV = KV
KY + 22 = x
KY = x - 22

Answer:
Step-by-step explanation:
C
3/4 =1/3 hour
how long to burn 2 and 1/2
3/4=1/3hour
1/4=1/9 hour
4/4=1=4/9hour
1/2=2/4
1/2=2/9hour
2 and 1/2=1+1+1/2=4/9+4/9+2/9=10/9=9/9+1/9=1+1/9=1 and 1/9
answer is C. 1 and 1/9 hour
