To solve this problem and calculate the area of the sphere, you must apply the following formulas:
Formula N° 1:
V=4/3(πr³)
V is the volume of the sphere (V=3,000π m³).
r is the radius.
Formula N° 2:
A=4πr²
A is the area of the sphere.
r is the radius.
As you can see, you don't have the value of the radius "r". So, you must rewrite the Formula N° 1, and clear "r":
V=4/3(πr³)
(3,000)(3)=4πr²
r³=9,000/4π
r=(9,000/4π)<span>^1/3
</span> r=13.1037 m
Then, to calculate the area of the sphere, you must substitute the value of "r" into the Formula N° 2:
A=4πr²
A=4π(13.1037)²
A=2,158 m²

The answer is: 2,158 m²

Step-by-step explanation:
This is 2 half circles so you can find the area of a circle and divide it by 2.
First circle has a diameter of 6 cm
6/2=3 cm
So, circle has radius of 3.
Area of circle= 3.14(pi) radius^2
3.14 x 3^2= 28.26
28.26/2=14.13 cm
Area of first half circle= 14.13
Repeat that process for the second circle.
3.14 x 2.5^2=19.625
19.625/2=9.8125
14.13+9.8215=23.9425
Area=23.9425

Answer:
Step-by-step explanation:
A common way of measuring the mass of objects is to use balance scales. A balance scale works by placing the object you want to weigh on one side and adding gram masses to the other side until the scales are level. Masses for weighing usually come as 1 g, 5 g, 10 g, 20 g or more!
