Hey there!

Formula: πr^2

r = radius

pi = 3.1415926535898 (but we can say it approximately equals 3.14)

Your equation (3.14)(4.2)^2 = answer

4.2^2 = 4.2 × 4.2 = 17.64

New equation: 17.64 × 3.14 = 55.3896

We round our answer to the nearest tenth

Answer: 55.4 ☑️

Good luck on your assignment and enjoy your day!

R(-9, 4) and S(2,-1); Find T.

madreJ [45]

Answer:

12.083 units

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (-9,4)$

$(x_2,y_2) = (2,-1)$

Replacing these values in the distance formula

$D =\sqrt{(-9-2))^2+(4-(-1))^2}$

$D =\sqrt{(-11)^2+(5)^2}$

$D =\sqrt{121+25}$

$D =\sqrt{146}$

$D= 12.083$

Hence the distance is 12.083 units
