Step-by-step explanation:
A
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter ) , then
C = 3.14 × 8 ≈ 25.12 in
B
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 94.2 , then
2πr = 94.2 ( divide both sides by 2π )
r = 
= 15 cm
Answer:
500 students.
Step-by-step explanation:
Since 150 students make up 30% of the school's student population, the equation 150/30=x/100. In order to find x, cross multiply x*30 and 150*100. Then set the two results equal to each other and solve. 15000=30x. 15000/30=500. x=500.
Step-by-step explanation:
Picture############
Seen 4 gallons are being turned into pints it easy just need to do 4x8 which = 32 because 1 gallons = 8 pints!
