4.5 times 10^10
1. Multiply 5times ten to the third
2. Multiply 9 times ten raised to the seventh
Then multiply them together
5000 times 90000000
6,00 because you have to add them up then divide the the last nimber and you should get 6,000
R^2=(x-6)^2+(y-4)^2
r^2=(6-2)^2+(4-1)^2, r^2=16+9=25
(x-6)^2+(y-4)^2=25
Answer:
a. 254.34, b. 56.52
Step-by-step explanation:
a. A = πr^2,
A = 3.14(9^2)
A = 3.14*81
A = 254.34
b. C = πd
C = 18*3.14
C = 56.52
