Answer:
V≈678.58cm³
Step-by-step explanation:
Area of a circle is pi * radius² so:
1) Area = pi * 5²
= 25pi ≈ 78.54 yd²
2) Area = pi * 7²
= 49pi ≈ 153.94 cm²
Circumference is 2 * pi * radius so:
3) Circumference = 2 * pi * 10
= 20pi ≈ 62.83 mi
4) Circumference = 2 * pi * 3.3
= 6.6pi ≈ 20.73 in
Volume of a rectangular prism is length * width * height
5) Volume = 10 * 3 * 10
= 100 * 3
= 300 yd³
6) Volume = 5 * 7 * 5
= 35 * 5
= 175 in³
Not completely sure on the triangular prisms though. I'm almost certain the formula is 1/2 * height * base 1 * base 2 though
Let S represent the cost of use of Silver Gym for a month.
Let F represent the cost of use of Fit Factor for a month.
Let T represent the number of training sessions used in the month.
S = 45 +25T
F = 75 +15T
We want to find T so the costs are equal.
.. S = F
.. 45 +25T = 75 +15T
.. 10T = 30 . . . . . . . . . subtract 45+15T
.. T = 3 . . . . . . . . . . . . divide by 10
Sarah would have to buy 3 training sessions to make the cost at the two gyms equal.
24 is a multiple of 6 because 1st of all, 6 goes into 24 and 24 does not go into 6 equally. 2nd of all, 6 x 4 = 24 so that means 6 is a factor of 24.
