Answer: 1,070 cm²
Step-by-step explanation:
25 multiplied by 15 is 375.
15 multiplied by 4 is 60.
25 multiplied by 4 is 100.
Now, we multiply these answers by 2.
375 multiplied by 2 is 750.
100 multiplied by 2 is 200.
60 multiplied by 2 is 120.
Add these all up, and you get your surface area, 1,070.
(Tldr; SA = 2lw + 2lh + 2hw)
Well, the formula for a triangle is base times height times 1/2. In this case it would be 21x30. That equals 630. Then, you divide 630 by 2 which is 315. Your answer would be 315 squared.
The answer is C.92 because 10x3 is 30,8x4 is 32,and 6x5 is 30 so the equation is 30+32+30
Answer:
185.04 mm
Step-by-step explanation:
The perimeter is 1/2 of the circumference plus the diameter
We need to go around the semicircle on the outside plus across the middle
1/2 C + d
1/2 2*pi * r + 2r
pi *r +2r
3.14 (36) + 2 (36)
113.04+72
185.04
Answer:
B. 2n + 1.
Step-by-step explanation:
This is an arithmetic series with first germ 3 and common difference 2.
The nth term (an) = a1 + d(n - 1)
= 3 + 2(n - 1)
= 2n + 3 - 2
= 2n + 1.
