What is the area of a flower pot that have the shape of a semi circle and its diameter 2.8cm?​
Firdavs [7]

Step-by-step explanation:

The area of a circle = pi r^2

d = 2r Divide by 2 to get the radius

r = d/2

The diameter = 2.8 cm

r = d/2

r = 2.8/2

r = 1.4

The area of the circle = pi * r^1

The area of the circle = 3.14 * 1.4^2

The area of the circle = 6.1544

But you are working with a semic circle

The area of a semicircle is 1/2 that of a circle

Area of semicircle = 1/2 6.1544 = 3.0772 =3.08 when rounded

Find the missing measures for the rectangle. l = _?_ w = 4.2 m A = 37.8 m2 P = _?_ A) 9 m; 26.4 m B) 14.7 m; 61.74 m C) 9 m; 13.
egoroff_w [7]

Answer:

The correct answer is A.

Step-by-step explanation:

The area of a rectangle can be calculated using the following formula:

Ar=W . I

If we know that the area measures 37.8 m^{2} and one side of the figure measures 4.2 m, we can say that:

37.8m^{2}=4.2m. I

We isolate the side we don't know:

\frac{37.8m^{2}}{4.2m} = I\\9 m = I

So I = 9 m

To know the perimter of a rectangle, we use the following formula:

P= I. 2 + W . 2

P= 9m. 2 + 4.2m. 2

P= 26.4 m

Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. They also found that increasing the intensity of light increased the number of electrons ejected, but not their speed.
