I'm guessing a pentagon but I could be wrong
Answer:
<h2>6.28</h2>
Step-by-step explanation:
<h2>Hi there</h2><h3>to understand this </h3><h3>you need to know about</h3>
- algebra
- circle
- area of semi-circle=½×πr²
it says to figure out the area of <u>semi-circle </u>not full circle
so
using the formula of area of semi-circle
<h3>=½πr²</h3>
=½×3.14 × 2²
=2×3.14
=6.28
a) You are given the rate as 7.4m/min,
The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.
b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.
c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:
41.36 = 7.4t
To solve for t, divide both sides by 7.4:
t = 41.36 / 7.4
t = 5.59 minutes ( 5 minutes and 35 seconds)
We develop the ratio between the number of milliliters present in 1 tablespoon and that is,
15 mL: 1 tablespoon
We let x be the number of millileter in 3 tbsp and it can be determined through the equation below.
x = 3 tbsp x (15 mL/ 1 tbsp) = 45 mL
Therefore, there are 45 mL in 3 tbsp.
