Answer:

56 cm^2

Step-by-step explanation:

Surface area is just finding the areas of each face in a figure. As we are given a net of a figure, it is much easier for us to calculate it.

Area of square base (side^2)

4^2 = 16 cm^2

Area of ONE triangular face (1/2 x b x h):

1/2 x 4 x 5 = 10 cm^2

Multiply that by 4 because we have 4 triangular faces: 10 cm^2 x 4 = 40 cm^2

ADD all the areas of triangles and square:

16 cm^2 + 40 cm^2 = 56 cm^2

HOPE THIS HELPS

Have a nice day!

When paid flat a round parachute has a diameter of 8 meters. What is the parachute’s circumference

mariarad [96]

Answer:

25.12 meters

Step-by-step explanation:

The circumference of a circle is given by

$c=2\pi r$ (1)

where:

$\pi\sim 3.14$

r is the radius of the circle

In this problem, the parachute has a diameter of 8 meters:

d = 8 m

The radius of a circle is equal to half of its diameter, so the radius of the parachute is:

$r=\frac{d}{2}=\frac{8}{2}=4 m$

And therefore, by applying eq.(1) we can find the circumference of the circle:

$c=2\pi r=2\cdot 3.14 \cdot 4 = 25.12 m$

How do I solve 6/2 + 8/3

Xelga [282]

Answer:

The solved given fractional expression is $\frac{17}{3}$

Therefore the given fractional expression becomes

$\frac{6}{2}+\frac{8}{3}=\frac{17}{3}$

Step-by-step explanation:

Given fractional expression is $\frac{6}{2}+\frac{8}{3}$

To solve the given fractional expression as below :

$\frac{6}{2}+\frac{8}{3}$

$=3+\frac{8}{3}$

$=\frac{3\times 3+8}{3}$

( here taking the term 3 as LCM )

$=\frac{9+8}{3}$ ( by adding the sums here )

$=\frac{17}{3}$

$\frac{6}{2}+\frac{8}{3}=\frac{17}{3}$

Therefore the solved given fractional expression is $\frac{17}{3}$

Therefore the given fractional expression becomes

$\frac{6}{2}+\frac{8}{3}=\frac{17}{3}$

The solved given fractional expression is $\frac{6}{2}+\frac{8}{3}=\frac{17}{3}$
