Considering it's volume of 113 cm³, the approximate radius of the sphere is given by:
A. 3 cm
<h3>What is the volume of an sphere?</h3>
The volume of an sphere of radius r is given by:
In this problem, we have that V = 113 cm³, hence the radius in cm is given as follows:
![r = \sqrt[3]{\frac{113 \times 3}{4\pi}}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B113%20%5Ctimes%203%7D%7B4%5Cpi%7D%7D)
r = 3 cm.
Hence option A is correct.

16 and 17. area is given. A=
use this relation to find radius
18.base=2, h=3.8 so, area=(1/2)*base*h=3.8 thats option D
19. area= base*h=12*7=84 option B
20.area of trapezoid= (1/2)h(a+b) where a and b are parallel sides.
so, area=(1/2)(3)(8.9+3.3)=(1/2)(3)(12.2)=3*6.1=18.3 option D
Answer: Day 9
Explanation:
480 - 40t = 140
340 = 40t
t= 8.5
The answer is by the end of the day, so it is Day 9.
Answer:
± 13
Step-by-step explanation:
= ± 13, since
13 × 13 = 169 and - 13 × - 13 = 169
According to the triangle inequality property, we know that the sum of two sides of a triangle is greater than the third side. Let's assume that the length of the side is x. That said, we can make the inequalities.
x + 3 > 5
8 > x
x + 5 > 3
this means that x >2, 8 > x, and x > -2. We can disregard the last inequality. We can now make an answer. We know that 2<x<8, so we can use any of those values in our answer. That makes our answer: 4 cm. and 6 cm.
