Calculate the surface area of the following shape. Round all calculations to the nearest whole number

total surface area = 672 cm^2

Step-by-step explanation:

radius of hemisphere, r = 7 cm

radius of base of cone, r = 7 cm

height of cone, h = 22-7 = 15 cm

slant length of cone, L = sqrt(7^2+15^2) = sqrt(274)

Area of the cone

= pi r L

= pi * 7 * sqrt(274)

= 115.87 pi

= 364.02 cm^2

Area of hemisphere

= 2 pi r^2

= 2 pi * 7^2

= 307.88 cm^2

Total surface area = 364.02 + 307.88 = 671.89 cm^2

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
