Answer:
6π
Step-by-step explanation:
(135/360)×π×4²
(135/360)×π×16
=6π
2.4=6x so isolated the variable, 2.4/6=0.4 so x=0.4
Step-by-step explanation:
3. The length of the rectangle is 3x and width is x+5
Now,
Area of rectangle=l×b
=3x(x+5)
=3x^2+15x(option d.)
4. 2/3x-4=20
2x/3=20+4
2x/3=24
2x=24×3
2x=72
x=72/2
x=36(option d.)
