The formula for circumference is 2πr.
C = 2(3.14)(119.3)
C = 749.204
Nearest tenth would be 749.20 mm
You could write 42/20 for #60.
Answer:
$6.49
Step-by-step explanation:
Pennies = 8% of 50 =4 ; 4x0.01 = 0.04
Dimes = 30% of 50 = 15 ; 15x0.10 = 1.50
Nickels = 10 + 4(number of pennies) = 14; 14x 0.05 =0.70
Quarters = 50 - 33 (total pennies + dimes + nickels ) = 17 ; 17x0.25=4.25
Therefore total amount in bag = 0.04+1.50+0.70+4.25 = $6.49
Answer:
C. 18°
Step-by-step explanation:
The <em>order of symmetry</em> (n) is the number of times a shape fits onto itself during a complete turn through 360°.
The <em>angle of rotational symmetry</em> (θ) is the smallest angle through which the shape must be rotated to coincide with itself.
To find the angle, y<em>ou divide the number of degrees in a circle by the order of symmetry</em>.
θ = 360/n
= 360/20
= 18°
