There are 2 circular bases: A = π r²
A = π (3)²
   = 9 π

There is one lateral face that is a rectangle: A = L x W
In this instance, the length equals the perimeter of the circle: L = 2 π r
A = 2 π (3) x 7
   = 42 π

Surface Area = 2(9 π) + 42 π
                       = 18 π + 42 π
                       = 60 π
                       ≈ 188

Are You guys up for math?? Its 6th grade math though!! so are you ready?? l want help please.
katen-ka-za [31]

The ratio would be 4:1.

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 64 and 16 is 16

Divide both terms by the GCF, 16:

64 ÷ 16 = 4

16 ÷ 16 = 1

The ratio 64 : 16 can be reduced to lowest terms by dividing both terms by the GCF = 16 :

64 : 16 = 4 : 1

Therefore:

64 : 16 = 4 : 1

Answer:

168 in², 94.25 yd²

Step-by-step explanation:

I couldn't find a formula for the SA of a triangular prism so I just found the area of each surface.

The formula for SA of a cylinder is 2\pi rh+2\pi r^{2}

All work for triangular prism is in the image

Moesha has 196 pepper plants that she wants to plant in square formation. How many peppers plants should she plant in each row?
miss Akunina [59]

Hey there!!

In order to solve this question, we take the area as 196 as these are the total number of plants to cover a specific place.

The formation must be in a square formation

area of a square = ( s ) ²

s = side

or the number of plants in a row

s² = 196

s = √196

s = 14

There are 14 plants in each row

Hope my answer helps!
