Given that the measurement is in centimeters, find the area of the circle to the nearest tenth. (Use 3.14 for π)( the radius is 5)
answers: A) 19.6 cm2
B) 31.4 cm2
C) 49.3 cm2
D) 78.5 cm2

D) 78.5cm 2

Step-by-step explanation:

To find area of a circle use the formula

Pi x radius squared

3.14 x 5 squared

3.14 x 25 = 78.5

The area of the circle is 78.5cm^2

Step-by-step explanation:

We will first extract the key information from the question asked:-

*** Find the area of the circle

*** The radius of the circle is 5cm

*** "π" should be taken as 3.14

***measurement must be in centimeters.

Firstly we need to understand what is meant by the area of a shape. The area of a shape is (circle, triangle, triangle , square etc) is basically the quantity of space that is situated or located inside the given shape. It can also mean the amount of space that is shut in and within the boundary of the shape.

The formula for finding this quantity of space that is within a circle (The area of a circle) is π × r^2.

We have already been given π as 3.14, the radius is 5cm, we will simply draft all these into the formula and solve to determine the area of this circle in question.

π×r^2 = 3.14 × 5 × 5

= 78.5cm^2

Therefore the area of the circle is 78.5cm^2

i dont know i just need points

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
