algol13

Answer:

31

Step-by-step explanation:

Here the trick is to perform the indicated operations in the correct order.  Anything inside parentheses must be done first, followed by any multiplication or division, followed by any addition or subtraction.

Doing the work inside parentheses first:

(3 × 22) ÷ 6 + [28 – (4)2]  =>  (66) ÷ 6 + [28 - 8], or

(66) ÷ 6 + [28 - 8]  =>  11 + [20], or 31

Answer: Circle.

Depending on the angle and the place of intersection, when a plane intersects a cube, the sections created may be a square, a pentagon, a trapezoid, a triangle or a rectangle (even you can obtain an octagon), but you will never get a circle.

Answer:

1. \frac{C}{D} = 3.143

2. Circumference

3. Area of the circle is 3850 cm^{2}.

   ii. Circumference of the circle is 220 cm.

Step-by-step explanation:

The area, A, and the circumference, c, of a circle can be determined respectively by:

A = \pir^{2}

C = 2\pir

where r is the radius of the circle.

1. the ratio of the circumference and diameter, D, of a circle is:

r = \frac{D}{2}

so that,

C = 2\pi\frac{D}{2}

C = \piD

\frac{C}{D} = \pi

   = \frac{22}{7}

   = 3.143

2. The distance around a circular region is known as it's circumference.

3. Given a circle of radius 35 cm, then:

A = \pir^{2}

   = \frac{22}{7} x (35)^{2}

   = \frac{22}{7} x 1225

   = 22 x 175

A = 3850

Area of the circle is 3850 cm^{2}.

C = 2\pir

   = 2 x \frac{22}{7} x 35

   = 2 x 22 x 5

   = 220

C = 220 cm

Circumference of the circle is 220 cm.
