I found the image that accompanied this problem.
We need to solve for the area of the sector.
A = n/360 * π * r²
A = 85/360 * 3.14 * 5²
A = 0.2361 * 3.14 * 25
A = 18.5347
Answer is C. 18.5 square meters.
Is this a test because you said your out of time
To write 0.1 as a percentage you have to multiply it by 100 and then put the % sign at the end of it.
0.1 X 100 = 10%
Answer:
2144.66in³
Step-by-step explanation:
Radius = 8 inches.
To determine the amount of sphere to make the ball, we'll have to find its volume.
Volume of a sphere = 4/3 * Πr³
V = 4/3*Πr³
Π = 22/7
V = 4/3 * 22/7 * 8³
V = 2144.66inches³
V = 2144.66in³
The amount of plastic required is 2144.66in³.
Two figures<span> that have the same shape are said to be </span>similar<span>. When two </span>figures<span> are </span>similar<span>, the ratios of the lengths of their corresponding sides are equal. We calculate as follows:
3.9 / 1.3 = 9.6 / b
b = 9.6 x 1.3 / 3.9
b = 3.2</span>
