1)
1/5 x 2/4
1x2=2
5x4=20
2/20 = 1/10
2)
8/3 x 1/4
8x1=8
3x4=12
8/12 = 2/3
3)
3 1/3 x 9/2
3 1/3 = 10/3
10x9=90
3x2=6
90/6 = 15/1 = 15
4)
5/2 x 1/4
5x1=5
4x2=8

The volume of a sphere is 1928π m3 . What is the surface area of the sphere to the nearest tenth?

Rufina [12.5K]

$\bf \textit{volume of a sphere}\\\\
V=\cfrac{4}{3}\pi r^3\qquad \begin{cases}
r=radius\\
------\\
V=1928\pi 
\end{cases}\implies 1928\pi =\cfrac{4}{3}\pi r^3
\\\\\\
1928\pi =\cfrac{4\pi r^3}{3}\implies \cfrac{3\cdot 1928\pi }{4\pi }
=r^3\implies 1446=r^3
\\\\\\
\sqrt[3]{1446}=r\\\\
-------------------------------\\\\
\textit{surface area of a sphere}\\\\
S=4\pi r^2\qquad r=\sqrt[3]{1446}\implies S=4\cdot \pi \cdot \sqrt[3]{1446^2}$

Which postulate proves that the two triangles are congruent? ASA SAS SSS AA

Rina8888 [55]

SSS congruence rule.

Solution:

Given ΔABC and ΔDEF are congruent.

To prove that on which rule they are congruence.

In triangle ABC,

AB = 2.5 cm, BC = 1.8 cm, CA = 1.8 cm

In triangle DEF,

DE = 2.5 cm, EF = 1.8 cm, FD = 1.8 cm

Consider ΔABC and ΔDEF,

AB = DE (Side)

BC = EF (Side)

CA = FD (Side)

∴ ΔABC ≅ ΔDEF (by SSS congruence rule)

Hence, the given triangles are congruent by SSS congruence rule.
