Answer:
22.3 km²
Step-by-step explanation:
The formula for the area of a circle is
A = πr²
r = ½d, so
A = π(½d)² = ¼πd²
A = ¼ × π × (16/3)² = ¼ × π × 256/9 ≈ 22.3 km²
You put the number of exes as the numbers below
Answer:
check for me beacause 90+10 equals -100% thanmyou.
X=36
you add 126 to 162 making it 288, then you minus 5 out of 13 making it 8. 288/8 =36
4πrsquare= 2πrsquare+2πrh
2πrsquare=2πrh
R=h
So h=16/2=8mm
