Answer:
It's 1 lap every 10 minutes, so 1/10
Step-by-step explanation:
3 3/4
= 3+ 3/4
= 3+ 0.75
= 3.75
The length as a decimal is 3.75 m~
94.985 using 3.14 or 95.033 using pie directly
Step-by-step explanation:
This is the answer if the radius is 5.5, half of 11. square it multiply by pie
For this, you have to understand the ratios of a 30,60,90 triangle. The ratio(in order) is x, x(sqrt 3), 2x (following the 30,60,90 pattern y'know). Well, we know the length of the hypotenuse, 4.2, so let's use ratios to figure the other sides out. The ratio of AC is x and the ratio of AB is 2x, so 2x/2=x=2.1. One side down. BC has a ratio of x(sqrt 3). We already know x so we can substitute it in. We get 2.1(sqrt 3). To calculate the area, use the formula 1/2(bh). Inputting the values in, we get 1/2(2.1*(2.1(sqrt 3)). This can be calculated to around 3.82. To calculate the perimeter, take the sum of the sides. By adding the sides together, we get about 9.98. Hope you can now understand how to do these kinds of questions.
