Answer:

11700 mm²

Step-by-step explanation:

Vertical height between the centres of top and bottom circles

sqrt[(2×28)² - 28²]

= 28sqrt(3)

Width of the rectangle

= 4×28

= 112

Length of the rectangle

= 28sqrt(3) + 2(28)

= 56 + 28sqrt(3)

Area = 112 × (56 + 28sqrt(3))

= 11703.71133 mm²

What is the volume of a right circular cylinder with a radius of 6 m and a height of 9 m?
geniusboy [140]

The volume of the right circular cylinder with a radius of 6 m and a height of 9 m is <u>1018 m²</u>.

The volume of a substance is the total space occupied by a three-dimensional object.

The volume of a right circular cylinder with a radius of r units and a height of h units is given by the formula <u>V = πr²h square units</u>.

We are asked to find the volume of the right circular cylinder with a radius of 6 m and a height of 9 m.

Substituting these values in the formula, we get Volume,

V = π(6)²(9) m² = 324π m² = 1017.876 m² ≈ 1018 m².

Therefore, the volume of the right circular cylinder with a radius of 6 m and a height of 9 m is <u>1018 m²</u>.

Angle A and Angle B are complementary angles. If angle B is five degrees more than four times angle A, find the measure of each
kupik [55]

<u>Answer</u>:

Angle A = 17°, Angle B = 73°

<u>Step-by-step explanation:</u>

Angle A & Angle B are complementary angles (given) so they will form 90°.

Let's take,

Angle A = x

Angle B = 4x +5 (angle B is five degrees more than four times angle A)

Measure of each angle=?

Angle A + Angle B = 90°

x + 4x + 5 = 90

5x + 5 = 90

5x = 90 - 5

5x = 85

x = 85 ÷ 5

x = <u>1</u><u>7</u><u>°</u>

Angle A = x = <u>1</u><u>7</u><u>°</u>

Angle B = 4x + 5 = 4(17) + 5 = 68 + 5 = <u>7</u><u>3</u><u>°</u>
