Answer:

3.14

Step-by-step explanation:

because the area of a circle is pi × r^2, we can just plug in the value of r which is 1 yard

A = pi × (1)^2

A = pi × 1

A = pi or 3.14

A caterpillar started at point (−2.5, −5.5) on a coordinate plane. She crawled in a straight line through the origin to point (4
alexgriva [62]

Answer:

The value of y is 99

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the line passes through the origin

therefore

Is a proportional variation

Find the value of k

with the point (-2.5,-5.5)

k=y/x=-5.5/-2.5=2.2

The equation is equal to

y=2.2x

so

For x=45

substitute

y=2.2(45)=99

Which equation can be used to find the unknown length, b, in this triangle?
Romashka-Z-Leto [24]

The equation for finding the hypotneus of a right triangle is
{a }^{2}  +  {b}^{2}  = c {}^{2}
so we know that 4²+b²=5²
so that would simplify as 16+b=25
so x=25-16
which is 9
so therefore we can conclude that
b = 9inches
