Find the area of the triangle. Figure is not drawn to scale. Show your work. (Image attached)

Zolol [24]

Answer: $13.8cm^2$

Step-by-step explanation:

The area of a triangle can be calculated with the formula:

$A_{(triangle)}=\frac{b*h}{2}$

The base of the triangle is "b" and the height of the triangle is "h",

In the figure you can observe that the base and the height of the triangle are:

$b=6.9cm\\h=4cm$

Knowing these values, you can substitute them into $A_{(triangle)}=\frac{b*h}{2}$ .

Therefore, the area of the triangle is:

$A_{(triangle)}=\frac{(6.9cm)(4cm)}{2}$

$A_{(triangle)}=13.8cm^2$

Find the lateral surface area of a

balandron [24]

Answer:

15.1 mm²

Step-by-step explanation:

Lateral surface area of a cylinder = 2πrh

(where r is the radius and h is the height)

Given:

r = 1.2 mm
h = 2 mm

Substitute given values into the formula:

⇒ Lateral surface area = 2π(1.2)(2)

= 4.8π

= 15.1 mm² (nearest tenth)
