Step-by-step explanation:

The equation representing the given statement is ~
The least number of lawns that he can cut and buy the computer is 10 lawns ~
Total savings should be greater or equal to $ 820 in order to buy the computer,
And his total savinga is equal to ~
Money he saved + money got from cutting lawns.
let's assume the lawns cut by Tyrod be x,
Money earned by cutting lawns is equal to
- total number of lawns cut × $50
total savings is equal to ~
hence,
by solving for " x (number of lawns cut) " we get ~
Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is
1. Is 8 seconds
2. I think is 15 quartz sorry if I’m wrong
Which two there’s no picyure
The lateral surface of a cylinder can be found with the equation
A = 2 π r h Substitute in your values.
A = 2 π (11) (7) Multiply 11 and 7.
A = 2 π (77) Multiply 77 and 2.
A = 154π Don't simplify anymore so you can keep pi in the answer.
The surface are uses the equation
A = 2 π r h + 2 π r² Substitute in your values.
A = 2 π (11) (7) + 2 π (11)² Simplify and multiply your terms.
A = 2 π (77) + 2 π (11)²
A = 154 π + 2 π (11)²
A = 154 π + 2 π (121)
A = 154 π + 242 π Since both terms are in terms of pi, you can combine them.
A = 396π Stop simplifying to leave the answer in terms of pi.
