AB/AD=AC/AE
4/7=AB/10
AB=4×10/7=40/7

from right circular cylinder with height 10 cm and radius of base 6 CM a right circular cone of the same height and base is remo
djyliett [7]

Answer:

753.98 cubic cm.

Step-by-step explanation:

We have been given that from right circular cylinder with height 10 cm and radius of base 6 cm, a right circular cone of the same height and base is removed.

To find the area of remaining solid we will subtract volume of cone from volume of cylinder.

\text{Volume of remaining solid}=\text{Volume of cylinder- Volume of cone}

\text{Volume of remaining solid}=\pi r^{2} h- \frac{1}{3}\pi r^{2}h

\text{Volume of remaining solid}=\frac{3}{3}\pi r^{2} h- \frac{1}{3}\pi r^{2}h

\text{Volume of remaining solid}=\frac{2}{3}\pi r^{2} h

Upon substituting our given values in the formula we will get,

\text{Volume of remaining solid}=\frac{2}{3}\pi*6^{2}*10

\text{Volume of remaining solid}=\frac{2}{3}\pi*36*10

\text{Volume of remaining solid}=2*\pi*12*10

\text{Volume of remaining solid}=240\pi

\text{Volume of remaining solid}=753.9822368615503772\approx 753.98

Therefore, the volume of remaining solid is 753.98 cubic cm.

A point is randomly chosen in the circle shown below.
quester [9]

Answer:

in a region with a letter

Step-by-step explanation:

For a certainty, then probability is 1.

That means sum of probability of all events in the sample space.

This means P(A)+P(B)+P(C)+P(D)=1

This is equivalent to:

P(A or B or C or D)=1

Hence for certainty, the region must be:

A or B or C or D

So the correct answer is in a region with a letter.

In the following triangle theta=60.Find the values of the angles of the angles B and B'
Contact [7]

Answer:

180-60 = 120 if triangle is not equilateral it cannot be isosceles then depending where the angles are they will show  60,60,60 if equilateral

For isosceles it would need to be 58 61 61 as 60, 60,60 cannot be isosceles.

Vectors 60 if right angled triangle = 90-60 = 30

So angles = 30 and 90 degree or just 120 if angle theta is a vector as explained below.

Step-by-step explanation:

Statement: If two vectors are represented by the sides of a triangle both in magnitude and direction taken in order, the resultant sum of the vectors is given by the closing third side of the triangle taken in the reverse order both in the magnitude and direction
