Answer:
398.2 cm²
Step-by-step explanation:
The area of the whole circle is ...
A = πr²
A = π(13 cm)² = 169π cm²
The 270° sector is 3/4 of the whole circle, so its area is ...
sector area = (3/4)(169π cm²) ≈ 398.2 cm²
The answer would be 6xz sqr2z
Answer:

Step-by-step explanation:
In order to solve for this equation we have to note a couple of things.
There is a diagonal square inside a larger square. The space formed by the smaller square not being in the larger square is a right triangle.
The side length of the smaller square (4) is also the hypotenuse of this triangle.
Since we know that the other side length of the triangle is 3, we can use the Pythagorean Theorem to find the value of b.
The Pythagorean Theorem states that
, where a and b are the legs and c is the hypotenuse.
We can substitute 3 in as a and 4 in as c and find b.




So b is
units long.
