Replace the x and y values in the given equation.

1. d = √((6-0)^2 + (8-0)^2

= √(6^2 + 8^2)

= √(36 + 64)

= √100

= 10

2. d = √((3-(-3))^2 + (5-2)^2

=√((3+3)^2 + 3^2)

=√(6^2 + 3^2)

= √(36 + 9)

= √45

=3√5 ( exact ) or as a decimal 6.7082 (round as needed)

3.  d = √((4-(-1))^2 + (-5-(-1))^2

= √((4+1)^2 + (-5+1)^2)

= √(5^2 + -4^2)

=√(25 + 16)

= √41 (exact) or as a decimal 6.4031 (round as needed)

Helpppp plzzz...plz give steps
uysha [10]

Answer:

Volume of hemisphere =

\frac{2}{3} \pi \: r {}^{3}

Given volume =

18\pi \: cube

\frac{2}{3}   \times \frac{22}{7}  \:  {r}^{3}  = 18 \times  \frac{22}{7}

So pi is there on both the sides so it will be cut from both LHS and RHS

\frac{2}{3}  \times r  {}^{3}  = 18

2 \times r {}^{3 }  = 18 \times 3

2 \times r {}^{3}  = 54

r {}^{3}  =  \frac{54}{2}

r {}^{3}  = 27

r = 3

Therefore value of r=3 inches

If you are helped with my answer pls tag me brianliest I really want it... Plzz

THANK YOU

In a triangle ABC if angle a = 60 °,angle<br> b= 60° then find c​
Mkey [24]

c = 60

Step-by-step explanation:

A triangle is a figure that has sum of all angles equals to 180

i.e ,

Angle A + Angle B + Angle C = 180

60 degree + 60 degree + Angle C = 180

Angle C = 180 - 60 - 60

Angle C = 60
