Answer:
option (a) ; 5 meters and 22 meters has the closest and reasonable approximation for the diameter and circumference of a circle.
Step-by-step explanation:
The circumference of a circle is given by the relation :
Circumference C = πd
Given that :
the diameter and circumference of a circle are as follows:
(a) 5 meters and 22 meters
(b) 19 inches and 50 inches
(c) 33 centimeters and 80 centimeters
We are meant to deduce the entity with the closest approximation.
a) 5 meters and 22 meters
Circumference C = πd
C = π × 5
C = 3.14 × 5
C = 15.7 meters
b) 19 inches and 50 inches
Circumference C = πd
C = π × 19
C = 3.14 × 19
C = 59.66 inches
c) 33 centimeters and 80 centimeters
Circumference C = πd
C = π × 33
C = 3.14 × 33
C = 103.62 centimeters
From the above calculations ; it is clear and obvious that the first option i.e option (a) which is 5 meters and 22 meters Has the closest and reasonable approximation for the diameter and circumference of a circle
Answer:
279 miles
Step-by-step explanation:
31 miles/gal * 9 gallons = 279 miles
So... notice the picture below, the arc is 350 miles long,
and the radius is 4000
Answer:
A
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Here f(x) is shifted 3 units left , then
f(x) → f(x + 3)
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here f(x) is shifted 4 units down , then
f(x) → f(x) - 4
Thus
f(x) = → f(x) = - 4
30% = 3/10
Number of hours you sleep = 24hours × 3/10
= 24hours ÷ 10 × 3
= 2.4hours × 3
= 7.2hours
Hope this helps! :)
