Answer:
8.062258
Step-by-step explanation:
d = 8.062258
For:
(-2, 3)
(5, -1)
Distance Equation Solution:
d=√(5−(−2))2+(−1−3)2
d=√(7)2+(−4)2
d=√49+16
d=6–√5
I belive the answer is
d=8.062258
Answer:
The correct option is 30.6
Therefore,
Area of Sector is 30.6 units².
Step-by-step explanation:
Given:
Central angle = θ = 142°
Radius = r = 5 units
pi = 3.14
To Find:
Area of Sector = ?
Solution:
If the θ measured in degree then the Area of Sector is given as

Where r = radius, θ = Central angle
On substituting the values we get



Therefore,
Area of Sector is 30.6 units².
Circumference
2*pi*r
2*(22/7)*(9/2)
2*(11/7)*9
198 / 7
28.28 cm
so 56.52 is not correct
Answer:
Volume=469cm³
Step-by-step explanation:
[tex]
Volume,V=Volume Cone + Volume\ of Hemisphere\\\\
Volume Cone,V1=\pi*r^2*\frac{h}{3}=\pi*4^2*\frac{12}{3}\\ \\
=201.06cm^3\\
Volume of Hemisphere,V2=2*\pi*\frac{r^3}{3}\\
=2*\pi*\frac{4^3}{3}=268.083cm^3\\
Volume=V1+V2=201.06+268.08\\
=469cm^3
