Answer:
First you find the radius R
We have, circumference = 2*3.14*R = 31.4
=> R =31.4/(2*3.14) =5
We have , area = 3.14*R^2 = 3.14*5^2 = 78.5
Step-by-step explanation:
Here we use pi =3.14.
Answer:
car 2

car2 costs less than $30,000
9514 1404 393
Answer:
(a) 145
Step-by-step explanation:
The measure of the angle marked x° is half the sum of the intercepted arcs:
(90° +200°)/2 = x° = 145°
55% of 1800 = 0.55(1800) = 990...so there are 990 girls in the school
30% of 990 = 0.30(990) = 297...so there are 297 girls who take the bus
