Question 7

serg [7]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - a cone with volume 769?3 ft³ , having a height of 15 ft

To calculate - radius of the cone

We know that ,

$\bold{Volume \: of \: cone = \frac{1}{3}\pi \: r {}^{2} h }\\$

substituting the values in the formula stated above ,

$\bold{769.3 = \frac{1}{3} \times 3.14 \times r {}^{2} \times 15} \\ \\\bold{\implies r {}^{2} = \frac{769.3 \times 3}{3.14 \times 15} } \\ \\\bold{\implies r {}^{2} = \cancel\frac{2307.9}{47.1}} \\ \\\bold{ \implies \: r {}^{2} = 49} \\ \\ \bold{\implies \: r = 7 \: ft}$

therefore ,

radius = 7 cm

Please help me with this

Dvinal [7]

Answer:

a. E = {1, 2, 3, 4, 5, 6, 7, 8}
b. A ∩ B = {2, 3}
c. A ∪ B = {1, 2, 3, 4, 5, 7, 8}

Step-by-step explanation:

Locate the designated space on the diagram and list all the numbers in it.

a. E = {1, 2, 3, 4, 5, 6, 7, 8} . . . . all numbers in the rectangle

b. A ∩ B = {2, 3} . . . . where the circles overlap

c. A ∪ B = {1, 2, 3, 4, 5, 7, 8} . . . . only 6 is outside the circles

Zane calculated the missing side length of one of these triangles using the Pythagorean Theorem. Which triangle is it?

topjm [15]

The pythagorean theorem states that for any RIGHT-ANGLED TRIANGLE, the relationship between the side lengths are A²+B²=C², where C is the hypotenuse :P

Which means that it can only be applied on right angled triangles~
So your answer would be B, a right-angled triangle.
