Answer:
My answer is 8. I just rounded if you don't want to round just go with 7.5.
Answer:
Step-by-step explanation:
Alright, lets get started.
The diameter of Pluto is given as 2274 kilometers.
The radius of Pluto will be half of he diameter.
Hence the radius of Pluto will be :
The formula of volume is :
Hence the volume is :
Hence the volume is : 6153890704.6 kilometers cube ..... Answer
Hope it will help :)

Answer:
Step-by-step explanation:
Circumcenter of A triangle is the center of a circle passing through the vertices of the given triangle.
So, the distance of Z from the vertices Q, R and S will be the radii of the circle.
Therefore, ZQ = ZR = ZS
Since, circumcenter of a triangle is defined by the point of intersection of the perpendicular bisectors of the sides of the given triangle.
Therefore, points W, X and Y are the midpoints of sides QR, RS and QS.
Using these facts,
a). QR = 2(WQ)
= 2(25)
= 50
b). Apply Pythagoras theorem in ΔRXZ,
(RZ)² = (RX)² + (ZX)²
(RZ)² = (40)² + (9)²
RZ = √1681 = 41
c). XS =
=
= 40
d). Since, ZQ = ZR = ZS
ZS = 41
e). By applying Pythagoras theorem in ΔRWZ,
(RZ)² = (WZ)² + (WR)²
(41)² = (WZ)² + (25)²
(WZ)² = (41)² - (25)²
WZ = √1056
WZ =
≈ 32.5
