Answer:
Area is = to 1017.88
Circumference is = to 113.1
Step-by-step explanation:
To find the area of a circle use the formula A=πr2
So . . .
A = π18²
A = π324
A = 1017.88
To find the circumfrence of a circle use formula C=2πr
So . . .
C = 2π18
C= 113.1

Answer:D
Step-by-step explanation:
<u>Answer:</u>
a. the error is that he wrote 0.05 instead of 0.2
0.148835 ≈ 0.2
b.
0.2 = 2 × 0.1
0.2 = 2 × 10⁻¹
The mass is about 2 × 10⁻¹ kg
I cannot see the equation
A (103)(109)
=103*109
=(10*10*10)*(10*10*10*10*10*10*10*10*10)
=10*10*10*10*10*10*10*10*10*10*10*10
=1012
=1000000000000
c.1e+23
