What is the volume of a sphere?

The volume of sphere is the measure of space that can be occupied by a sphere. If the radius of the sphere formed is r and the volume of the sphere is V. Then, the volume of the sphere is given by: Volume of Sphere, V = (4/3)πr³

Given that, the radius of a sphere is 11 cm.

Here, the volume of sphere = (4/3) ×π×(11)³

= 1.33×π×1331

= 1770.23π

≈ 1770π cm³

Therefore, the volume is 1770π cm³.

If x = 9 units and h = 5 units, then what is the area of the triangle shown?

A.
12.5 square units
B.
45 square units
C.
67.5 square units
D.
22.5 square units

Answers

Answer:

The answer is D, 22.5 sq. Units

Step-by-step explanation: This is because to get the area of a triangle you multiply b x h and then divide by two. So 9 times 5 = 45. Then you divide by two and 45 ÷ 2 = 22.5

Hope this helps.

D. just substitute 5 as a and 9 as b which gets 45 then divide it by 2 equals 22.5

Answers

0.4 is the answer because you if you work backwards and use inverse operations you get 0.4.
meaning, if you divide 0.9 by 9, you get 0.1. when you multiply 0.1 and 8 you get 0.8. and when you subtract 0.4 from 0.8 you get your answer, 0.4.
