Answer:
141.4
Step-by-step explanation:
Plug the numbers into the formula, V=πr2h, you know that your radius is 3 and your height is 5, so you get V=π(3)2(5), you just then put it in the calculator. You get 141.37, round to the nearest tenth 141.4
Answer: C, because I’m assuming you meant 84°.
Explanation: 2+6+7 is equal to 15. The three angles of a triangle will always add up to 180, so you need to divide 180 by 15, which is 12. Then, multiply each number (2, 6, and 7) by 12 to get your answer, which is 24, 72, and 84 :)
You are correct the answer is a:18
Answer:
1. 20
2. 0
Step-by-step explanation:
1. 20
11 -12÷4+3 (6-2)
Brackets first
11-12÷4+3 x 4
Then division and multiplication
11-3+12
Subtraction next
8+12
Now addition
8+12=20
2. Anything divided by 0 is 0
#13
P=2L+2W
We know that L=26, W=21
so
Perimeter, P = 2(26)+2(21) = 52 + 42 = 94 feet
