Find the area of a circle with a radius of 8.

201.06

Step-by-step explanation:

Area of a circle = pi x r^2

= 201.06

200.96cm²

Step-by-step explanation:

Given

Radius of the circle =8cm

To Find

area of the circle

Formula used

area of circle = πr²

Solution

area of circle = π r²

area of circle= π (8)²

area of circle = π64

as π =3.14

therefore

area of circle 64 x 3.14cm²

area of circle = 200.96cm2

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
