Answer:
d = 18, c = 56.55
Step-by-step explanation:
Solution
d=2r=2·9=18
C=2πr=2·π·9≈56.54867
Answer:
A2+B2=C2
90^2+120^2=C2
8100+14400=22500
you need to find the square root of 22500 and therefore get 150
the area would be 5,400
p.s. love your profile picture
surface area = 5ab +5bh
a = 4
b=7
h=18
5*4*7 = 140
5*7*18 = 630
630+140 = 770 square meters
