Answer:
divide the diameter by 2
Step-by-step explanation:
the equation for the area of a circle is Pi times the radius squared. the radius is half the diameter, so if you need to find the area of the circle, just divide the diameter by 2 and you will have the length of the radius. then, jut plug it in to the equation.
Answer:
9x(4+8y+3y)
Step-by-step explanation:
36x+72xy+27xy
9x(4+8y+3y)
7/10s of 40 would be 28 so that leave 12 hours to work inside
Answer:
20
Step-by-step explanation:
we see here that angle RPN is 180 degrees. SPM is 90 degrees so
angle RPS + angle SPM + angle MPN = 180 degrees
(4y - 10) + 90 + y = 180
(4y - 10) + y = 90
5y - 10 = 90
5y = 100
y = 20
