Answer:
4m
Step-by-step explanation:
- v=4/3 pi r^3
- substitute 267.95=4/3×3.14×r^3
- 267.95= 12.56r^3/3
- multiply by the reciprocal on both sides 64=r^3
- find the cuberoot on both sides to remove the cube hence 4=r

Explanation:
The given passage talks about the impact of chemicals on the ecosystem. The speaker narrates how the ecology belongs to plants, animals, and humans, though man seemed intent to destroy it for himself.
The blanks in the given passage are filled with the appropriate words as follows-
Ecology is the study of how <em><u>(1) plants</u></em>, animals, and people live <u><em>(2) together</em></u> and help each other. But man sometimes forgets he <em><u>(3) is</u></em> a part of the <u><em>(4) family</em></u> of all living things. Here is an example. A planter is <u><em>(5) talking</em></u> about killing <u><em>(6) weeds</em></u> on his land. He remembers his first <u><em>(7) experience</em></u> with a weedicide. He was a <u><em>(8) planter</em></u> then, working <u><em>(9) on</em></u> a rubber plantation. He had a problem with weeds. The cost of weeding of the <u><em>(10) fields</em></u> by hand was getting <em><u>(11) too</u></em> high. So he used a new, cheap, and effective <u><em>(12) method</em></u>, good old Sodium Arsenate. He sprayed plenty of this <em><u>(13) around</u></em> to kill the weeds. The first thing to <em><u>(14) react</u></em> were the frogs.
Answer: so what are u asking?
Step-by-step explanation:
Answer: 28*63
Step-by-step explanation:
- If first you want the answer, you must divide and then you would get 63.
- Then you take 63 and multiply 28 and you'll get 1,764

(For question 27)
Answer: Exactly square root 58 inches
Step-by-step explanation: The dimensions given for the right angled triangle are 7 inches and 3 inches respectively. The third side is yet unknown. However what we know is that a right angled triangle can be solved by using the Pythagoras theorem which states that,
AC^2 = AB^2 + BC^2
Where AC is the longest side. The question requires us to calculate the longest side and with the other two sides already known, the Pythagoras theorem now becomes,
AC^2 = 7^2 + 3^2
AC^2 = 49 + 9
AC^2 = 58
Add the square root sign to both sides of the equation
AC = square root 58 inches
