Answer:
339.336 m^2
Step-by-step explanation:
Given data
Radius= 6meters
We know that the surface area of a half-sphere is given as
A=3πr^2
A= 3*3.142*6^2
A= 3*3.142*36
A=339.336 m^2
Answer:
x = 0
Step-by-step explanation:
From the intersecting secants theorem, If from an exterior point, we draw two secant segments to a circle, then the product of the length of one secant segment and its external secant part will be equal to the product of the length of the other secant segment and its external secant portion.
Thus, applying it to this question;
(x + 27 + 48) × (x + 27) = (x + 45)²
(x + 75)(x + 27) = x² + 90x + 2025
x² + 102x + 2025 = x² + 90x + 2025
Like terms will cancel put to give;
102x - 90x = 0
12x = 0
x = 0/12
x = 0
Answer:
60
Step-by-step explanation:
the 6 in 7639 has a value of 600
600/10 = 60
The height of glass 1 which in cylindrical in shape is 7.6 centimeters. Since the total volume of water added by Celia is 100 cubic centimeter, and the volume of glass 2 is 26.4 cubic centimeter which is a conical in shape. Subtracting the volume of glass 2 from the total volume glass 1 can be calculated and its height.
