Answer:
3.1in
Step-by-step explanation:
Radius: r=2in
Perimeter of circle: p=2×pi×r=4×pi
Perimeter of figure: p1=p/4=pi=3.14in
Best approximation: 3.1in
Answer:
2396
Step-by-step explanation:
Let the diameter = d
Let the height = h
Formula
Metric Tons = k * d^4 / h^2
Solution
Metric Tons = 64
d = 2
h = 9
k = ?
(You can't do the second part by not using a ratio unless you put k in and solve for it)
64 = 2^4 k / 9^2
64 = 8 *k / 81
64 * 81 / 8 = k
5184 / 8 = k
k = 648
Solve for the second example
Metric Tons = d^4 * k / h^2
Metric Tons = ?
d = 5
h = 13
k = 648
Metric Tons = 5^4 * 648 / 13^2
Metric Tons = 625 * 648 / 169
Metric Tons = 2396 rounded.
The scuba diver's position relative to sea level after the 4.6 minutes is 5.1 ft.
Given:
A scuba diver descends in the water at a rate of 23 1/2 feet per minute for 2.6 minutes.
A scuba diver ascends at a rate of 28 feet per minute for 2 minutes after seeing a big fish.
To find :
The scuba diver's position relative to sea level after the 4.6 minutes.
Solution:
Rate of a scuba diver descending in the water for 2.6 minutes = 
Distance covered by a scuba diver in 2.6 minutes = 
Rate of a scuba diver ascending for 2 minutes = 
Distance covered by a scuba diver in 2 minutes = 
The position of scuba diver after 4.6 minutes relative to sea level:
The scuba diver's position relative to sea level after the 4.6 minutes is 5.1ft.

Answer:
Step-by-step explanation:
Raheem , stuart and tommy share £594, the ratio of the amount of money raheem gets to amount of money tommy gets is 4:6. Raheem gets £108 less than tommy, how much does each person get.
Let the Amount of money
Raheem got = x
Tommy = y
Raheem gets £108 less than tommy
x = y - 108
The ratio of the amount of money raheem gets to amount of money tommy gets is 4:6.
Sum of Proportion =
4 + 6 = 10
=
