Answer:

2nd option

› 56.25π cm²

Step-by-step explanation:

<u>we know , </u>

area of circle is πr²

so,

<u>given,</u>

diameter,d = 15cm

radius,r = d/2 = 15/2 = 7.5 cm

so,

area = πr²

= (7.5×7.5)π

= 56.25π cm²

i hope you find it helpful !!!!

Answer:

56.25 pi  cm^2

Step-by-step explanation:

To find the area of the circle,

we use the formula

A = pi r^2, where r is the radius

We know the diameter is 15 so we can find the  radius from

r = d/2  where d is the diameter

r = 15/2

A = pi ( 15/2) ^2

A = pi ( 225/4)

A = 56.25 pi  cm^2

The graph of f ′ (x), the derivative of f of x, is continuous for all x and consists of five line segments as shown below. Given
Rom4ik [11]

f'(x)\ge0 for all x in [-3, 0], so f(x) is non-decreasing over this interval, and in particular we know right away that its minimum value must occur at x=-3.

From the plot, it's clear that on [-3, 0] we have f'(x)=-x. So

f(x)=\displaystyle\int(-x)\,\mathrm dx=-\dfrac{x^2}2+C

for some constant C. Given that f(0)=7, we find that

7=-\dfrac{0^2}2+C\implies C=7

so that on [-3, 0] we have

f(x)=-\dfrac{x^2}2+7

and

f(-3)=\dfrac52=2.5
