The radius of a circle is 4 m. Find its area in terms of <br> π<br> π.

wlad13 [49]

Answer:

16π

Step-by-step explanation:

Given:

$\text{Radius of circle}: 4 \ \text{m}$

<u>Formula:</u>

$\text{Area of circle} = \pi r^{2}$

Replace the radius in the formula:

$\implies \text{Area of circle} = \pi (4)^{2}$

Evaluate the area:

$\implies \text{Area of circle} = \pi (4)(4)$

$\implies \text{Area of circle} = 16\pi$

Since the question says to determine the area in terms of π, the final answer is 16π.

Please show the steps I need this right now I’m taking a test8(x−4)<7x−3

Olegator [25]

Answer:

x < 29

Step-by-step explanation:

8(x−4)<7x−3; distribute 8 in the parenthesis

8x - 32 < 7x - 3; subtract 7x from both sides

x - 32 < -3; add 32 to both sides

x < 29

Perpendicular lines intersect to form four right angles. never always sometimes

natima [27]

Answer:

Always

Step-by-step explanation:

The definition of a perpendicular line is that it intersects another at a 90 degree angle. Using this, by verticals, the opposite corner angle must also be 90-degrees, and since one side of a line is 180 degrees, 180-90 = 90, which ensure the rest of the angles will be 90 degrees too.
