Step-by-step explanation:
so you can find the perimeter of a circle
-----The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle, you need to go halfway around the circle and then across a diagonal to get back to where you started, so the perimeter is 1/2 π × d + d.
Answer:
d) 87
Step-by-step explanation:
to solve this lets set up the equation

253+x=340
and subtract 253 on both sides
x=87
to double check take the averages
(87+85+70+98)/4=85
