Answer:

Hello! answer: 12.56

Step-by-step explanation:

Area for circles is found be doing

radius × radius × pi since we arent given radius we have to figure it out. But what we do know it diameter is just 2 times the radius so to undo that to find our radius we just do 4 ÷ 2 and 4 ÷ 2 = 2 so 2 is our radius now we will square it which is just fancy for multiply is by itself so 2 × 2 = 4

4 × 3.14 = 12.56 So 12.56 is our area! Hope this helps you!

Answer: There are 104 silvery minnow population in the Rio Grande River.

Step-by-step explanation:

Since we have given that

Number of tagged silvery minnows = 54

Number of captured silvery minnows = 62

It includes 12 tagged silvery minnows.

So, Number of silvery minnows without tags = 62 -12 =50

So, Good estimate of the silvery minnow population in the Rio Grande River would be

$54+50\\\\=104$

Hence, there are 104 silvery minnow population in the Rio Grande River.

Find the surface area of the pyramid .The surface of the pyramid is _ in2 (Type a whole number .)

garik1379 [7]

Given the figure of a square pyramid

The area pf the base =area of the square of side 14 in =

$14\cdot14=196in^2$

the area of the sides = 4 times the area of a triangle of a base of 14 in and a height of 12 in

so, the area of the sides =

$4\cdot\frac{1}{2}\cdot\text{base}\cdot\text{height}=4\cdot\frac{1}{2}\cdot14\cdot12=336in^2$

So, the surface area of the pyramid =

$196+336=532in^2$

So, the answer will be A = 532 in^2
