Answer:

210 m²

Step-by-step explanation:

The area of a rhombus is d₁ * d₂ * 0.5. In other words, the area is its diagonals multiplied together and divided by 2.

Substitute the measures of the diagonal given.

35 * 12 * 0.5 = 210

The area is 210 m²

I hope this helps! Feel free to ask any questions!

Why is (D₁ + D₂)/2 incorrect?

Find the volume in cm^3 of a right circular cylinder with a radius of 10 cm and height of 14 cm

yawa3891 [41]

4398.22 cm³ the volume of cylinder.

What is volume of cylinder?

'Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
The unit of volume is in cubic units such as m3, cm3, in3 etc.

Given,

Height of cylinder = 14 cm

radius of cylinder = 10 cm

Now using formula volume of the cylinder = π r² h

put value in formula,

3.14 × 10× 10 × 14 = 4398.22 cm³

Therefore, 4398.22 cm³ the volume of cylinder.

What is the answer to 10-(8p+3)=9(2p-5) ?

aniked [119]

Use distribution.
10 - (8p + 3) = 10 - 8p - 3 = 7 - 8p
9(2p - 5) = 18p - 45

So...
-8p + 7 = 18p - 45
Subtract 7 from both sides
-8p = 18p - 52
Subtract 18p from both sides
-26p = 52
Divide both sides by -26.
p = -2

There's your answer :D

The length of a rectangle is 3 1/6 cm longer than the width. The perimeter of the rectangle is 15 1/3 cm. What are the width and

ahrayia [7]

The width of rectangle is $2\frac{1}{4}$ cm and length is $5\frac{5}{12}$ cm.

Step-by-step explanation:

Let,

Width of rectangle = w

Length of rectangle = $w+3\frac{1}{6}=w+\frac{19}{6}$

Perimeter of rectangle = $15\frac{1}{3}=\frac{46}{3}$ cm

Perimeter = 2(Length + Width)

$\frac{46}{3}=2(w+\frac{19}{6}+w)\\\\\frac{46}{3}=2(2w+\frac{19}{6})\\\\\frac{46}{3}=4w+\frac{19}{3}\\\\4w+\frac{19}{3}=\frac{46}{3}\\\\4w=\frac{46}{3}-\frac{19}{3}\\\\\ 4w=\frac{46-19}{3}\\\\4w=\frac{27}{3}\\\\4w=9$

Dividing both sides by 4

$\frac{4w}{4}=\frac{9}{4}\\\\w=\frac{9}{4}$

Width of rectangle = $\frac{9}{4}=2\frac{1}{4}\ cm$

$Length = w+\frac{19}{6}=\frac{9}{4}+\frac{19}{6}\\\\Length = \frac{27+38}{12}=\frac{65}{12}\\\\Length=5\frac{5}{12}\ cm$

The width of rectangle is $2\frac{1}{4}$ cm and length is $5\frac{5}{12}$ cm.
