Mathematics
1 answer:
Sliva [168]3 years ago
6 0

Answer:

31

Step-by-step explanation:

For rectangle ABCD, AC and BD are the lengths of the diagonals. The diagonals of a rectangle are congruent.

AC = BD

3x + 7 = 131 - x

Add x to both sides.

4x + 7 = 131

Subtract 7 from both sides.

4x = 124

Divide both sides by 4.

x = 31

A cone has a base radius of 2 millimeters and a height of 24 millimeters.
pishuonlain [190]
<span>The answer is D. 32? mm3. The volume of the cone is: V = 1/3 * π * r^2 * h, where r is the radius and h is the height. We know that: r = 2 mm and h = 24 mm. Therefore, the volume of the cone is: V = 1/3 * π * r^2 * h = 1/3 * π * 2^2 * 24 = 1/3 * π * 4 * 24 = 1/3 * π * 96 = 32 π mm^3.</span>

ioda

Answer:

Add 1,105.28 + 200.96 + 200.96.

Step-by-step explanation:

we know that

The surface area of the cylinder is equal to

SA=2B+LA

where

B is the area of the circular base

LA is the lateral area

In this problem we have

B=200.96\ mm^{2}

LA=1,105.28\ mm^{2}

substitute

SA=2(200.96)+1,105.28

SA=1,105.28+200.96+200.96

SA=1,507.2\ mm^{2}
