Answer:

Step-by-step explanation:

Bottom triangle

Area = b * height

b = 4 + 4 = 8 cm

h = 5.75

Area = 1/2 * 5.75 * 8

Area = 23 cm^2

Trapezoid

b1 = 8

b2 = 4

h = 2

Area = (b1 + b2)*h/ 2

Area = (8 + 4)*2 /2

Area = 12

Total area = 23 + 12

Total area = 35

Blababa [14]

Answer: V = 100\pi in^{3} (third option)

Given Information:

  • V = \frac{1}{3}\pi r^{2} h <-- volume formula.
  • r = 5
  • y = 13
  • <em>h = ?</em>

To find h...

  • h, r, and y make a right triangle.
  • h and r are the two legs, y is the hyptenuse.
  • h^{2} + r^{2} = y^{2}
  • h^{2} + 5^{2} = 13^{2}
  • h^{2} + 25 = 169
  • h^{2} = 144
  • h = 12

Use formula:

  • V = \frac{1}{3}\pi r^{2} h
  • V = \frac{1}{3} \pi (5)^{2} (12)
  • V = \frac{1}{3} \pi (25)(12)
  • V = \frac{1}{3} \pi (300)
  • V = 100\pi

3(2x+1)=21 <br> Solve this multi-step equation using the distributive property
Tasya [4]
3 (2x + 1) = 21
6x + 3= 21
-3 -3
6x = 18

Divide each side by 6, and x equals 3.

3 (2(3) + 1) = 21
3 (6 + 1) = 21
18 + 3 = 21


Hope this helps! Can I please have brainliest so I can level up? Thank you!
