Answer:
a
Step-by-step explanation:
Detailed Answer:
Diameter = Radius * 2
Radius = Diameter/2
a) 64cm
r = 32 cm
Diameter = 32 * 2 = 64cm
b) 25.2 m
r = 12.6 m
Diameter = 12.6 * 2 = 25.2 m
c) 29.5 in
r = 14 3/4 = 14.75
Diameter = 14.75 * 2 = 29.5 in
d) 64 cm
r = √32 cm^2 = 32 cm
Diameter = 32 * 2 = 64 cm
e) 49.32 ft
r = 24.66 ft
Diameter = 24.66 * 2 = 49.32 ft

Answer:
y = -x + 3
Step-by-step explanation:
y = x - 3 This equation has a slope of 1
A line that would be perpendicular to the above line would then need a slope of -1
If the line has a slope of -1 and passes through (2, 1) then we can plug into
y = mx + b to get the 'b' value
1 = (-1)(2) + b
1 = -2 + b
3 = b
Equation would be y = -x + 3
