I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.

The surface area is calculated based on the surfaces which are visible from the outside. In this case, you only need to calculate the surface of lateral side on the cone, the surface of lateral side on the cylinder, and the circle on the lower base of cylinder.

Write the expression to find the surface area
sa = lateral side of cone + lateral side of cylinder + circle
sa = (π × r × s) + (2 × π × r × t) + (π × r²)

Input the numbers
sa = (π × 1 × 3) + (2 × π × 1 × 2) + (π × 1²)
sa = 3π + 4π + π
sa = 8π
sa = 8 × 3.14
sa = 25.12

to the nearest tenth
sa = 25.1

The surface area of the composite solid round is 25.1 m²

Eric has $100,000 in savings account.The interest rate is 8 % per year and is not compounded.To the nearest Dollar,how much will
Roman55 [17]

Answer:

To calculate the simple interest, we say

S.I = (PxRxT)/100

Where P = the principal amount

R= rate in terms of %

And T= time.

Now P= $100 000

R= 8%

T= 3 years

S.I= (100,000 x8 x3)/100

=$2 400 000/100

= $24, 000

So the interest is 24000

Total amount he will be having = 100000 + 24 000

The total money he will be having in 3 years time = $124 000
