Answer:
Part a) The lateral area is
Part b) The area of the two bases together is
Part c) The surface area is
Step-by-step explanation:
we know that
The surface area of a right cylinder is equal to
where
LA is the lateral area
B is the area of the base of cylinder
we have
Part a) Find the lateral area
The lateral area is equal to
substitute the values
Part b) Find the area of the two bases together
The area of the base B is equal to
so
the area of the two bases together is
Part c) Find the surface area of the cylinder
we have
substitute
Subtract 59.99 from 64.19.
64.19 - 59.99 = 4.20
<u>The tax she paid was $4.20, so now we need to find the percentage.</u>
Divide 4.20 by 59.99.
4.20 ÷ 59.99 = 0.07
Multiply 0.07 by 100 to find the percentage.
0.07 × 100 = 7
<u>The sales tax in the area was 7%.</u>
If an ant has six legs, then:
- Two ants have 12 legs
- Three ants have 18 legs
- Four ants have 24 legs
- Five ants have 30 legs
- Six ants have 36 legs
- Seven ants have 42 legs
- Eight ants have 48 legs
- Nine ants have 54 legs
So, if you saw between 35 and 50 legs, there are between six and eight ants.
20% of the students chose a cupcake = 20 / 100: Shade 20 squares.
20 / 100 = x / 55
100x = 1100
x = 11 students who chose a cupcake
Hope this helps!! :)
