Answer:
Evan has $560 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $236.27. He buys 3 bicycle reflectors for $14.61 each and a pair of bike gloves for $15.56. He plans to spend some or all of the money he has left to buy new biking outfits for $57.65 each.
Step-by-step explanation:
:)
9000 millimeters because there are 1000 millimeters in one meter, so 9x1000 equals 9000.
From the information we have the diameter of the circle is 10 cm.
Area of a circle is given by 1/4π d²
A = 1/4 π d²
π = 3.14
d² = 10² = 100
So we now calculate.
A = 1/4 × 3.14 × 100
A = 0.25 × 3.14 ×100
A = 78.5 cm²
Using radius :
The radius of this circle is 10 ÷ 2 = 5
A = π r²
A = 3.14 × 5²
A = 3.14 ×25
A = 78.5 cm²
So we still get the same answer.
Both are correct
I accidentally got rid of the other things so I now have to type 20 characters so i can actually answer it
Answer:
height = 5.4 units
Step-by-step explanation:
r = 4.5/2 = 2.25
B = πr² = 3.14(2.25²) = 15.90
V = 1/3Bh
28.63 =1/3(15.90)h
85.89 = 15.90h
h = 5.40 units
