Dashboard / My courses / MAr1510-24-Ex10 / Welcome Message / MAT15 Find the area of a sector of a circle with central angle \( 60^{\circ} \) if the radius of the circle is 3 m . Choose the correct option.

a. Points A and B are 1.5 units apart. (Type an integer, fraction, or mixed number.) b. Give the coordinates of one point that is 4 units from point \( C \) in the x-direction. \( \square \) (Type an ordered pair.)

(Unit-AL) Uma célula esférica se dividiu em duas, preservando o volume total. Usando-se \( \sqrt[3]{2} \cong 1,26 \), se preciso, é correto estimar que o raio de cada uma das novas células será, em comparação com o da célula original, cerca de A. \( 20 \% \) menor. B. \( 30 \% \) menor. C. \( 40 \% \) menor. D. \( 50 \% \) menor. E. \( 60 \% \) menor.

VI. Determine the equation of the straight line in ordinary form that passes through the point \( (-2,5) \) and is parallel to the line \( 3 x-y=10 \).

Defina o que é o raio de um círculo e como ele se relaciona com o diâmetro.

The coordinates of triangle \( A B C \) are \( A\left(-4 \frac{1}{2},-2 \frac{1}{2}\right), B\left(-4 \frac{1}{2},-1\right) \), and \( C(6,-1) \) a. What is the distance between points A and \( B \) ? b. Give the coordinates for two points that are 4 units from point \( C \).
