Make an equation.
80% = 0.8
'of' is multiplication
'what number' is 'x'
'is' is an equal sign
0.8 * x = 64
0.8x = 64
Divide 0.8 to both sides:
x = 80

18
Step-by-step explanation:
original 3:4
now 18:24
Multiply by 6
Step-by-step explanation:
A =nr²
=3.14 × (80/2)
=3.14 × 40
= 125.6yd²
Since we know that in π radians there are 180°, thus how many radians in 132°?
