Use formula A²+B²=C²
120²+62²=C²
14,400+3,844=C²
14,400+3,844=18,244
√18,244=135.07035...
135.07035...≈135.1
Answer:
The correct answer is Total Cost Payable = $Exp + $15, where $Exp is the total price of the groceries bought by Barbara
Step-by-step explanation:
Barbara orders her groceries. Let us consider that she orders groceries worth $Exp from a store.
Extra charges levied by the store for delivering the groceries to Barbara's house is $15.
Thus the total payable charge by Barbara for her groceries should include the total price of the groceries and the delivery charges levied by the store.
Thus the Total Cost Payable by Barbara is the sum of the total expenditure by her on the groceries and the delivery charge.
∴ The total cost payable = $Exp + $15.
Answer:
The radius, r₂, of the ball that uses one-half the amount of rubber coating used to cover the 16-inch ball is approximately 4.66 inches
Step-by-step explanation:
The dimension of the ball with known radius = 16-inch
The surface area of the ball with 16-inch radius = 4×π×r² = π·D² = π×16² = 804.24772 in.²
Given that the ball uses one-half the rubber material coating used to cover the 16-inch ball, we have the surface area of the ball = 804.24772 in.²/2 = 402.12386 in.²
The radius, r₂ of the new ball is found as follows;
402.12386 in.² = 4×π×r₂²
r₂² = 402.12386 in.² /(4×π) ≈ 32
r₂ = √32 = 4·√2 ≈ 4.66 inches
The radius, r₂, of the ball that uses one-half the amount of rubber coating used to cover the 16-inch ball ≈ 4.66 inches.
