Answer:
Radius, r = 2.80 cm
Step-by-step explanation:
Given the following data;
Volume of cylinder = 207 cm³
Height = 8.4 cm
Pie, π = 3.14
To find the radius of the water bottle;
Mathematically, the volume of a cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a cylinder.
r represents the radius of the cylinder.
h represents the height of the cylinder.
Substituting into the formula, we have;
207 = 3.14 * r² * 8.4
207 = 26.376r²
r² = 207/26.376
r² = 7.85
r = √7.85
Radius, r = 2.80 cm
Answer:
136
Step-by-step explanation:
(2*6*3*4)-8 = 144-8
= 136
Answer:
, 61/100
Step-by-step explanation:
First we need to add all of the fractions before or at the 1980s, they have the same denominator, so we simply just add. It comes out to 39/100. Subtract 39 from 100 and we get 61 out of 100 or 61/100 or 61%.
3/4 + 2/4 (1/2) equals 5/4
And 5/4 is the same thing as 10/8
So 10/8 - 5/8 is 5/8
Answer:
4
Step-by-step explanation:
2 · 4 = 8
8 + 4 = 12
the value of x is 4
