First get the semiperimeter.
Perimeter of the figure = 1/2 Circumference + the diameter.
pi = 3.14
d = 6 yds.
Circumference of the circle of a full circle = pi * d
Circumference full circle = 3.14 * 6
Circumerence full circle = 18.84 yards.
The semi circumference = 1/2 the Circumference.
The semi circumference = 1/2 18.84
The semi circumference = 9.42 yards.
That's not the complete answer.
You must add the diameter to this.
Perimeter = Semi circumference + d
Perimeter = 9.42 + 6
Perimeter = 15.42 meters
Answer:
The time taken before the police force the robbers off the road is 1.5 hours
Step-by-step explanation:
The speed with which the robbers were travelling = 70 miles per hour
The speed with which the police went after the robbers = 90 miles per hour
The distance with which the robbers were in front of the police before the police came after them = miles
Let t represent the time in hours the police force the robbers off the road, we have;
30 + 70 × t = 90 × t
30 = 90 × t - 70 × t = (90 - 70) × t = 20 × t
30 = 20 × t
20 × t = 30
t = 30/20 = 1.5
t = 1.5 hours
The time taken before the police force the robbers off the road = t = 1.5 hours
Answer:
1 inch.
STEP BY STEP EXPLANATION:
We are given with the following equation r=(3V/πh)^1/2. By the picture we know that "V' is volume which translated to 5 in this problem, "π" is 3.14 and "h" is out height or 4in (in the picture we get all this values).
Therefore everything that there is left is to substitute and answer.
r = (3[5]/3.14[4])^1/2 - multiply the numbers
r = (15/3.14[4])^1/2 ~ (15/12.56)^1/2 -convert the decimal into a fraction and keep going
....
I must say the answer is 1 because it's rounded it's an approx. because the exact number the problem gives us is 1.09 rounded ends up being just 1

Answer:
175
Step-by-step explanation:
A glass and a half is 1+1/2 = 3/2 glasses.
2 1/2 glasses is 2/2 glasses more than that, or 5/2 glasses.
5/2 glasses is 5/3 times the size of 3/2 glasses, so there will be 5/3 the number of calories:
... (105 calories) × (5/3) = 175 calories
