Circumference  =   2pi  * r

So

3pi   =  2pi  r               divide  away pi

3  =  2  r

(3/2)  =  r    =   1.5 m

Area  =  pi  ( r^2)   =   pi  (1.5)^2   =   2.25 pi   m^2   ≈  7.07  m^2

Suppose T: ℝ3→ℝ2 is a linear transformation. Let U and V be the vectors given below, and suppose that T(U) and T(V) are as given
ira [324]

Answer:

T(3u+2v)=(-10,29)

Step-by-step explanation:

T is a linear transformation, hence it is homogeneous (T(cr)=cT(r) for all real c and r∈ℝ³) and additive (T(r+s)=T(r)+T(s), for all r,s∈ℝ³). Apply these properties with r=3u and s=2v to obtain:

T(3u+2v)=T(3u)+T(2v)=3T(u)+2T(v)=3(-2,5)+2(-2,7)=(-6,15)+(-4,14)=(-10,29)

We don't have an explicit definition of T, so it's more difficult to compute T(3u+2v) directly without using these properties.

A water and sprinkle our sins water out in a circular pattern how many feet away can it spread water if the area formed by the w
ludmilkaskok [199]

Answer:

11  feet away.

Step-by-step explanation:

Given:

A water and sprinkle our sins water out in a circular pattern

Area formed by the watering pattern is 379.94 square feet

To find:

How many feet away can it spread water means we have to find distance from the middle point to the last end of circular pattern of water sprinkling (radius of a circle) = ?

solution:

By using ,Area of a circle = \pi r^{2}

Area of a circle = 379.94 square feet  (given)

\pi r^{2} = 379.94

3.14\times r^{2}  = 379.94\\

Dividing both side by 3.14

r^{2}  = \frac{379.94}{3.14}  = 121

Taking square root both side

r = \sqrt[2]{11\times11}        (Taking common)

r = 11

Therefore, radius = 11

Thus,  it can  spread water 11  feet away.

Help me w how to solve math problems like these pls
leonid [27]

Answer:

x = 72

Step-by-step explanation:

For all polygons, the exterior angles add up to 360°

Since a pentagon has 5 exterior angles, you do

angle = 360 ÷ 5 = 72
