Mary is making a pinata that has a ball-like shape. The pinata has a surface area of 60 square feet. Use the formula for the surface area of a sphere:
S=471?
to find the radius of the pinata in feet.

2.19 ft

Step-by-step explanation:

The formula for the surface area of a sphere = 4πr²

Surface area of the sphere = 60 ft²

The formula to find the radius of a sphere

= √A/4π

= √60/4 × π

= 2.19 ft

Therefore, the radius of the pinata = 2.19 ft

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
