7 0

Answer:

201.1 mm²

Step-by-step explanation:

given that the diameter is 16mm,

radius = diameter ÷ 2 = 16÷2 = 8 mm

area of a circle is given by

A = πr², where

π=3.142

r = radius = 8 mm

Substituting these into the equation,

A = πr²

= 3.142 (8)²

= 201.088 mm²

= 201.1 mm² (rounded to nearest tenth)

Elis [28]

The area of a circle is given in terms of its radius by

 A = π · r²

Your circle has r=4 (half the diameter) and you want π=3.14. Using these values in the formula gives

 A = 3.14 · 4²

This matches your first selection

 3.14 · 4²

Write the exact value solution and an approximation for 10^4x=25
Murrr4er [49]

Answer:

exact value: x= \frac{log25}{4}

approximate: x=0.349485

Step-by-step explanation:

Exact Value:

10^{4x} = 25

log (10^{4x})= log 25

4x = log 25

x= \frac{log25}{4}

Approximate:

x= \frac{log25}{4}

x=1.39794/4\\

x=0.349485
