Find the surface area of a sphere with a radius of 3.6 inches. Use 3.14 for pi. Round your answer to the nearest hundredth, if necessary
that was wrong, the answer as 162.78
The formula to find the surface area of a sphere with radius r is 4πr².
Substitute r = 3.6 inches into the formula:
Surface Area = 4π(3.6)²
Surface Area = 4π(12.96)
Surface Area = 51.84π
Use 3.14 for pi:
Surface Area ≈ 51.84 * 3.14
Surface Area ≈ 162.4896
Rounding to the nearest hundredth:
Surface Area ≈ 162.49
The surface area of the sphere is approximately 162.49 square inches.
To find the surface area of a sphere, you can use the formula:
Surface area = 4πr^2
Where r is the radius of the sphere.
In this case, the radius is given as 3.6 inches, and π is approximated as 3.14.
To calculate the surface area, you can substitute the values into the formula:
Surface area = 4 × 3.14 × (3.6)^2
Next, square the radius:
Surface area = 4 × 3.14 × 12.96
Multiply the resulting value by 4:
Surface area ≈ 51.47 square inches
Therefore, the surface area of a sphere with a radius of 3.6 inches is approximately 51.47 square inches.
I apologize for the mistake in my previous response.
Let's calculate the surface area correctly:
The formula to find the surface area of a sphere with radius r is 4πr².
Substituting r = 3.6 inches into the formula:
Surface Area = 4π(3.6)²
Surface Area = 4π(12.96)
Surface Area ≈ 51.84π
Using the value 3.14 for π:
Surface Area ≈ 51.84 * 3.14
Surface Area ≈ 162.7536
Rounding to the nearest hundredth:
Surface Area ≈ 162.78
Therefore, the surface area of the sphere with a radius of 3.6 inches is approximately 162.78 square inches.
