Your answer is 21 for this one.
Answer:
138.16 in²
Step-by-step explanation:
The surface area SA of the cone is the sum of the base area B and the lateral area LA. The lateral area is half the product of the circumference and the slant height. The radius is half the diameter, so is 4 inches.
SA = B + LA
= πr² + (1/2)(2πrh) . . . . where h is the slant height
= (πr)(r +h)
Filling in the numbers, you have ...
SA = (3.14)(4 in)(4 in + 7 in) = 3.14×(44 in²) = 138.16 in²
Answer:
The answer is 8 : 22, 12:33 as they are two equelivant ratios 11 and 4
Answer:
88:132:44
Step-by-step explanation:
Divide 264 by 6 (2+3+1) = 44
2*44=88
3*44=132
1*44=44
The a value affects the graph by vertically stretching or compressing the graph.
The r and s values affect the zeros, or x intercepts of the parabola, and therefore the vertex.
Hope this helps!
