aliya0001 [1]

Answer:

The total surface area of a cylinder is equal to the sum of areas of all its faces. The total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder.

TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units

(7.RP.3) When invested at an annual interest rate of 6% an account earned $180.00 of simple interest in one year. How much money

tresset_1 [31]

Answer: f) $3,000

Step-by-step explanation:

Given: Simple interest amount S.I.= $180.00

The rate of interest annually= 6%

In decimal , the rate of interest annually r = 0.06

Time period t = 1 year

Let 'P' be the principal amount invested in account.

The formula to calculate simple interest is as :-

$\text{Simple interest }=Prt$

$\\\Rightarrow180=P(0.06)\times1\\\\\Rightarrow\ P=\frac{180}{0.06}\\\\\Rightarrow\ P=\$3000$

Hence, the principal amount invested in account = $3000
