What is the volume of the figure

Mathematics
1 answer:
Rufina [12.5K]3 years ago
4 0

Answer:

2411.52 cm³

Step-by-step explanation:

V = (2/3)πr³        Use the equation for volume of a hemisphere

V = (2/3)(3.14)(8)³     Simplify the exponent

V = (2/3)(3.14)(512)   Multiply

V = 1071.79 cm³

V = πr² h/3                   Now find the volume of the cone

V = (3.14)(8)²(20/3)      Simplify the exponent

V = (3.14)(64)(20/3)      Multiply

V = 1339.73 cm³

Add both of the volumes together to get the volume of the figure.

1071.79 + 1339.73 = 2411.52 cm³

Look at the diagram. If RS= 8y + 4, ST = 4y + 8, and RT = 36, find the value of y.
vladimir2022 [97]
<span>RS= 8y + 4, ST = 4y + 8, and RT = 36

RS + ST = RT
</span>8y + 4 + 4y + 8 = 36
12y + 12 = 36
12y = 24
    y = 2

answer
y = 2 (first choice)

I will give you 100 points if you can answer this<br><br> (66×578)÷3368=55÷77=???
erma4kov [3.2K]
(66✖️578) ➗ 3368=55➗77

P parentheses
E exponents
M multiplication
D division
A addition
S subtraction

You would do (66✖️578) first since it is in parentheses
66✖️578=38,148

38,138➗3368=55➗77
Since there are no exponents or multiplication you would do division

38,138➗3368= 11.3236342
55➗77=0.7

11.32 does not equal 0.7
So this equation would be false

Hope this helps! :3

CAN ANYBODY HELP ME OUT
bija089 [108]

Answer:

Correct option is

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.

Step-by-step explanation:

Here, we are given the line RQ, which is divided in two equal parts by a line PS which is perpendicular to RQ.

The foot S of PS is on the line RQ.

First of all, let us do a construction here.

Join the point R with P and P with Q.

Please refer to the attached image.

Now, let us consider the triangles  PQS and PRS:

  • Side QS = RS (as given)
  • \angle PSR = \angle PSQ = 90^\circ
  • Side PS = PS (Common side in both the triangles)

Now, Two sides and the angle included between the two triangles are equal.

So by SAS congruence we can say that \triangle PRS \cong \triangle PQS

Therefore, the corresponding sides will also be equal.

RP = QP

RP is the distance between R and P.

QP is the distance between Q and P.

Hence, to prove that P is equidistant from R and Q, we have proved that:

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.
