314cm

Step-by-step explanation:

The area of a circle = πr^2

where π = 3.14

r = radius

From the question, we've been given the radius as 10cm. So, we plug the radius into the formula.

Area= πr^2

= 3.14 × (10 × 10)

= 3.14 × 100

= 314 cm

Step-by-step explanation:

Given a composite figure,

A circle of radius r = 10cm

We want to find the area of the circle?

Area of a circle is calculated using

A = πr²

Where π is given to be 3.14

π = 3.14

And r is the radius of the circle

Then, area of the composite figure is

A = πr²

A = 3.14 × 10²

A = 3.14 × 100

A = 314 cm²

The last option is correct

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°

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
