Answer:
96π or 301.59 in³
Step-by-step explanation:
V(cone) = 1/3πr²h
= 1/3·π·6²·8
= 96π or 301.59
René Descartes provided the first systematic link between Euclidean geometry and algebra.
<h3>What is Geometry?</h3>
This branch of mathematics involves the study of object shape, their spatial relationship and that of their surrounding space.
René Descartes is referred to as the father of analytic geometry due to him establishing the relationship between Euclidean geometry and algebra.

0•47 as an ordinary number
Answer:
Anna and Ojo will have same amount after 13 days.
Step-by-step explanation:
Given that:
Anna has 300 naira
She saves 50 naira per day.
Let,
x be the number of days.
y be the amount saved
y = 50x + 300
Ojo has 1860 naira
He spends 70 naira per day.
Let,
x be the number of days
y be the amount left
y = 1860 - 70x
For equal amount, the equations will be equal
50x +300 = 1860 - 70x
50x + 70x = 1860 - 300
120x = 1560
Dividing both sides by 120
Hence,
Anna and Ojo will have same amount after 13 days.
Look at this like a right triangle with a height of 32 M and the angle at the base of 22 degrees
The distance from the boat to the lighthouse would be the base of the triangle
to find the base given the height and angle given the formula is
x = height / tan(angle)
x = 32 / tan(22)
x = 79.2 Meters
