Answer:
1.15
Step-by-step explanation:
tan θ=−4/7, and 270°<θ<360°
θ is in 4th quadrant
sec θ = 8.06 / 7 = 1.15

Answer:
<h3>The radius is 7 cm</h3>
Step-by-step explanation:
Volume of a sphere is given by

where r is the radius
From the question V = 1436 cm³

Multiply through by 3
We have

Divide both sides by 4π


Find the cube root of both sides
![r = \sqrt[3]{ \frac{1077}{\pi} }](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B1077%7D%7B%5Cpi%7D%20%7D%20)
r = 6.99
We have the final answer as
<h3>r = 7cm</h3>
Hope this helps
U should add a picture to solve it
When working with very large or very small numbers, scientists, mathematicians, and engineers use scientific notation to express these quantities. Scientific notation is a mathematical abbreviation, based on the idea that it is easier to read an exponent than to count many zeros in a number. Very large or very small numbers need less space when written in scientific notation because the position values are expressed as powers of 10. Calculations with long numbers are easier to do when using scientific notation
