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

wlad13 [49]

Answer:

16π

Step-by-step explanation:

Given:

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

Formula:

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

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.

Evaluate the expression. 5^2−4⋅6+11 Enter your answer in the box.

mart [117]

Explanation:

This question's it's about the order of operations. P-parenthesis, E-exponents, M-multiply, D-divide, A-add, and S-subtract. It can also go left to right.

Do exponents first.

$5^2=5*5=25$

$25-4*6+11$

Then, multiply left to right.

$4*6=24$

$25-24+11$

And add/subtract left to right.

$25-24=1$

$1+11=12$

$\boxed{=12}$

Hope this helps!

Thanks!

Have a great day!
