Answer:
i. Curved surface area = 2310
ii. Total surface area = 3696
iii. volume = 12936
Step-by-step explanation:
Perimeter of the circular base = circumference of the circle = 132 cm
circumference of a circle = 2r
132 = 2r
r =
=
r = 66 x
= 3 x 7
= 21
radius = 21 cm
vertical height, h = 28 cm
Thus applying the Pythagoras theorem,
=
+
= +
= 784 + 441
= 1225
l =
l = 35 cm
The slant height is 35 cm.
i. Curved surface area = rl
= x 21 x 35
= 22 x 3 x 35
= 2310
curved surface area of the cone is 2310 .
ii. Total surface area = +
rl
= r(r + l)
= x 21 (21 + 35)
= 22 x 3 x 56
= 3696
The total surface area of the cone is 3696 .
iii. volume of a cone = h
= x
x
x 28
= 12936
The volume of the cone is 12936
The money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000
<h3>What is compound interest?</h3>
The formula for compound interest is given as;
P = principal interest = $25, 000
r = rate = 4. 5%
n = 2 months
t = 6 years
A =
A =
A =
A = $20, 625, 000
Thus, the money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000
