A. True, a rhombus is a parallelogram with equal sides. A rhombus has four congruent sides.

B. True, but there are two other ways to find the area of a rhombus: there is the "diagonals" method and the "trigonometry" method.

C. False, the area of a rhombus is not less than the area of a parallelogram because it will depend on the diagonals.

D. False, a parallelogram is not always a rhombus because the dimensions and other attributes of a parallelogram may vary while the rhombus will remain equal for all aspects.

E. True, if you use the base times height formula but if you used any of the other formulas this would be false.

Find

Sedaia [141]

Answer:

The amount of steel used = 94.38 $m^{2}$

Step-by-step explanation:

Height of the tank = 4.5 m.

Diameter of the tank = 4.2 m.

But,

radius = $\frac{diameter}{2}$

= $\frac{4.2}{2}$

radius = 2.1 m

Total surface area of a cylinder = 2 $\pi$ rh + 2 $\pi$ $r^{2}$

= 2 $\pi$ r(r + h)

= 2 x $\frac{22}{7}$ x 2.1 (2.1 + 4.5)

= 44 x 0.3 (6.6)

= 87.12

Total surface area of a cylinder = 87.12 $m^{2}$

Since $\frac{1}{12}$ of the steel was wasted, then;

$\frac{1}{12}$ x 87.12 = 7.26 $m^{2}$

Actual area of steel sheet used = 87.12 + 7.26

= 94.38 $m^{2}$

Thus, 94.38 $m^{2}$ of steel was used in making the tank.

Keisha swims 18 feet from one side of her circular pool to the other swimming straight through the center. She then swims one ti

Ket [755]

Answer:

56.5 ft

Step-by-step explanation:

Here we know that:

- Keisha swims 18 feet from one side of her circular pool to the other swimming straight through the center --> this means that the diameter of the swimming pool is 18 feet, so

d = 18 ft

- Then, she swims one time around the entire edge of her swimming pool. --> this means that she swims along the perimeter of the swimming pool

The perimeter of a circle is given by

$p=\pi d$

where d is the diameter. Therefore in this case, the length of Keisha's second swim is:

$p=\pi \cdot d = 3.14 \cdot 18 =56.5 ft$
