Answer:
5.2 × 
Step-by-step explanation:
a number in scientific notation is expressed as
a × 
where 1 ≤ a < 10 and n is an integer
write 0.0052 as a number between 1 and 10, that is 5.2
we have to the move the decimal point 3 places to the left to retain it's value
3 places left means n is - 3
0.0052 = 5.2 × 
Answer: A=448+196pi, P=60+14pi
Step-by-step explanation:
I'm assuming that the figures which appear to be semicircles are semicircles and that the quadrilateral is a rectangle.
The perimeter is 16 + 16 + 28 + (28/2)(pi)= 60+14pi
area is area of rectangle + area of semicircle
= (16)(28)+(pi)(14)(14)=448+196pi
