Answer:

cone: 138.16 in²

pyramid: 352 m²

Step-by-step explanation:

Use the appropriate formula from your list of area and volume formulas.

Area of a Cone

A = πr(r +h) . . . . . where r is the radius and h is the slant height

The radius is half the diameter, so is 4 inches.

A = π(4 in)(4 in + 7 in) = 44π in² ≈ 138.16 in²

Lateral Area of a Square Pyramid

A = 2sh . . . . . where s is the side length of the base and h is the slant height

A = 2(8 m)(22 m) = 352 m²

Answer:

Step-by-step explanation:

To start of u have to subtract 150 with 180 which is 180 (cuz its a straight line and E to get angle S

Now that we know that 180-150= 30

We add S and R then subtract by 180

so 80+ 30= 110

then we said subtract 180

180-110= 70

Now we know that angle Q is 7-

Then the bottom is RS & SE (NOT REALLY SURE)

It is a Remote Interior Angle
