Answer:
78cm
Step-by-step explanation:
d = 10
area of a circle = πr^2
22/7 × 5 × 5
78.5cm
The product of 8 and 90 is 720 because 0 x 8 is 0 and 9 x 8 is 72 so when you multiply the two together you get 720.
I hope this helps you
width w
length w+11
perimeter =2 (width +length )
86=2 (w+w+11)
43=2w+11
32=2w
w=16
length = w+11=16+11=27
I think its A!! But im not sure
