Answer:

$360\ cm^2$

Step-by-step explanation:

Step 1: Determine the area of the bottom rectangle

$A = l * w$

$A = 10\ cm * 12\ cm$

$A = 120\ cm^2$

Step 2: Determine the area of the back rectangle

$A = l * w$

$A = 10\ cm * 5\ cm$

$A = 50\ cm^2$

Step 3: Determine the area of the top rectangle

$A = l * w$

$A = 10\ cm * 13\ cm$

$A = 130\ cm^2$

Step 4: Determine the area of the triangle

$A = \frac{h*b}{2}$

$A = \frac{5\ cm * 12\ cm}{2}$

$A = \frac{60\ cm^2}{2}$

$A = 30\ cm^2$

Step 5: Determine the surface area

$120\ cm^2 + 50\ cm^2 + 130\ cm^2 + 2(30\ cm^2)$

$360\ cm^2$

Answer: $360\ cm^2$

In an aquarium, the ratio of sharks to dolphins is 3 : 5 and the ratio of

Molodets [167]

Step-by-step explanation:

step 1: how many dolphins

there are 6 sharks

sharks to dolphins is 3 to 5

3 S to 5 D

we can divide 6 (amount of sharks known) by 3, to get what a ratio of 1 is

6 ÷ 3 = 2

so 2 sharks is = 1 part or ratio

now we can times by 5 to get a ratio of 5

5 × 2 = 10

there are 10 Dolphins

Step 2: How many starfish

repeat the steps above but for the ratio 2: 7 where 2 is the Dolfin ratio and there are 10 dolphins

How do i find the surface area of a cylinder with a radius of 3.5 ft. and a height of 14 ft.

Karolina [17]

The formula for the surface area of a cylinder is:
2πrh + 2πr^2

If we substitute in the measurements that we know, you get:

2 $\pi$ (3.5) (14) + 2 $\pi$ (3.5)^2

If we simplify this expression, we get:

98 $\pi$ + 24.5 $\pi$

If you simplify once more, you get

122.5 $\pi$ or ≈ 384.85

Therefore, the surface area is 122.5 $\pi$ or about 384.85
