The formula for the surface area is given and as follows.
SA = (2)(3.14)(r^2) + (2)(3.14)(r)(h)
The radius of the cylinder is 4 inches and the height is 9 inches. Using the given values, we can plug them into the formula and solve for the surface area from there.
SA = (2)(3.14)(4^2) + (2)(3.14)(4)(9)
SA = (6.28)(16) + (6.28)(36)
SA = 100.48 + 226.08
SA = 326.56 in^2
Hope this helps!! :)
Answer:
x = 127 degrees
Step-by-step explanation:
By the external angle of a triangle theorem:-
x + 5 = 79 + m < ACB
m < ACB = 180 - x, so:-
x + 5 = 79 + 180 - x
2x = 79 + 180 - 5 = 254
x = 127 ( answer)
Alto earned $ 225 and Sheryl earned $ 250.
Given that Alto and Sheryl both worked hard over the summer, and together they earned a total of $ 475, and Sheryl earned $ 25 more than Alto, the following calculation must be performed to determine how much each one earned:
- S = A + 25
- A = A
- A + 25 + A = 475
- 2A = 475 - 25
- A = 450/2
- A = 225
- S = 225 + 25 = 250
Therefore, Alto earned $ 225 and Sheryl earned $ 250.
