Answer:

Step-by-step explanation:

To convert radians to degrees

degree = radian × $\frac{180}{\pi }$ , then

$\frac{3\pi }{2}$ × $\frac{180}{\pi }$ ( cancel π on numerator/ denominator )

= $\frac{3(180)}{2}$

= $\frac{540}{2}$

= 270° → C

erastova [34]

Step-by-step explanation:

let the base be x

height= 6cm

area of a parallelogram= b×h= 48cm²

b×h=48

x×6=48

x= 48÷6

x=8

therefore, the base of the parallelogram is 8cm
