Answer:
7 : 17.29
Step-by-step explanation:
==>Given:
Two similar cylinders:
Surface area of Cylinder A = 49cm²
Surface area of Cylinder B = 121cm²
==>Required:
Scale factor between both cylinders
==>Solution:
We can easily get the scale factor between both by taking the following steps:
=>Set up a ratio of their surface area:
Smaller cone surface area : larger cone surface area
49:121
= 49/121
=>Simplify the ratio gotten:
Dividing the denominator and the numerator by 7, would give us,
7/17.29
= 7:17.29
Answer:
(-10,3),(9,0)
Step-by-step explanation:
So,
All we have to do is multiply the dimensions given.
15 * 14 * 9 = 210 * 9 = 1890
The volume of the cooking compartment of the oven is 1890 in.³
Answer:
n°
Step-by-step explanation:
Your selection is correct. Once again, they are alternate angles, meaning they're equal to one another.
Answer:
In the given two column proof two sides and included angles are equal.
Triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles .In the figure sides BD≅BD , AB≅ BC and <ABD ≅,BDD Therefore triangle ABD and triangle CBD are congruent by SAS property of congruence.
