Your answer would be 45 centimeters ^2

Answer:

45 centimeters squared (45 square centimeters - same thing)

Explanation:

First we need the area of each shape

To find the area of a right triangle we multiply the length of the legs and then divide by 2 - ab/2

Triangle 1: 6 centimeters squared

Triangle 2: 9 centimeters squared

To find the area of a rectangle you multiply the length by the width - lw

Rectangle: 30 centimeters squared

Now we add the values together:

6 + 9 + 30 = 45 centimeters squared

That is my answer, if you need anything else or more clarification I will edit this :)

if the sum of the first 60 positive integers is s, what is the sum of the first 120 integers in terms of s? a. 2s 3600 b. s^2 36
kvasek [131]
For the first 60 positive integers, a = 1, n = 60, l = 60.
Sn = n/2(a + l)
s = 60/2(1 + 60) = 30(61)

For the next 60 positive integer, a = 61, n = 60, l = 120
Sum = 60/2(61 + 120) = 30(61 + 120) = 30(61) + 30(120) = s + 3600

Sum of first 120 positive integers = s + s + 3600 = 2s + 3600

What is the surface area of a cylinder with a base radius of 3 ft and a height of 5ft
Solnce55 [7]
SA of a cylinder: 2\pir² + 2\pirh
r = radius of base
h = height of cylinder

Plug in 3 for r and 5 for h in the formula.
2\pi3² + 2\pi(3)(5)
Use a calculator to solve.

2\pi3² + 2\pi(3)(5) = 150.8 ft²

What is the exact volume of the figure?
uranmaximum [27]

Answer: 890.12 cm^3

Step-by-step explanation:

The formula for the volume of a cylinder is

V=\pi *r^2*h

V=628.3185307 cm^3

or simply

V=628.32 cm^3

Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.

Next, the formula for the volume of a sphere is

V=\frac{4}{3} \pi *r^3

so the volume of a hemisphere is half of that or:

V=\frac{2}{3} *\pi *r^3

V= 261.7993878 cm^3

or simply

V=261.80 cm^3

Finally, you add both of the volumes together to get

V= 890.1179185 cm^3

or simply

V=890.12 cm^3

A triangle has side lengths of 11 cm and 7 cm. Which could be the value of the third side, 19 cm or 17 cm ?
9966 [12]

Answer:

By the triangle side length theorem, the sum of the two shorter sides has to be equal to or larger than the third side. Thus, we can write the following inequation.

a

+

b

≥

c

, where a and b are the shorter sides and c the longest.

11, 9 and 15 satisfies this inequality while 11, 9 and 20 doesn't.

Justification:

The reason for this rule is simple; it's because if the longest side is longer than the sum of the two shorter sides, this means that the shorter sides aren't long enough to connect with the longest side, thus rendering the shape a collection of lines and disqualifying the possibility of having a triangle, which was our objective.

Practice exercises:

Which of the following triangles is possible?

a) 4,6 and 14

b) 5,11 and 16

c) 1,3,6

D). 12,19 and 26

Find the smallest possible value of a to make the following an actual triangle :

a

,

14

,

25

Hopefully this helps:
