The diameter of a circle is 10 m. Find its area to the nearest tenth.

78.54 m^2

Step-by-step explanation:

The computation of the area of the circle is shown below:

As we know that

Area of the circle = πr^2

Also

Diameter = 2r

10 = 2r

r = 5

So, the area of the circle is

=  3.14 × 5^2

= 78.54 m^2

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
