Answer: volume = 4275π m³

Step-by-step explanation:

The composite figure shown in the diagram is made up of a hemisphere at the top and a cone at the bottom.

Therefore,

Volume = volume of hemisphere + volume of cone.

The formula for determining the volume of a hemisphere is expressed as

Volume = 2/3πr³

Diameter of hemisphere = 30m

Radius = diameter/2 = 30/2 = 15m

Volume of hemisphere = 2/3 × π × 15³ = 2250πm³

The formula for determining the volume of a cone is expressed as

Volume = 1/3πr²h

h = height of cone = 33m

r = 15 m

Volume = 1/3 × π × 15² × 33

Volume = 2475π m³

Volume of the composite figure is

2250π + 2475π = 4275π m³

Due soon!! <br>Find the measure of GE¯¯¯¯¯¯¯¯. A. 14 B. 20 C. 15 D. 16
Nataly_w [17]

Answer:

D. 16

Step-by-step explanation:

GH^2 = GF \times GE

12^2 = 9 \times (9+x - 2)

144= 9 \times (7+x)

\frac{144}{9}= (7+x)

16= 7+x

16-7=x

9=x

GE = 9 + x - 2 = 9 + 9 - 2 = 18 - 2

GE = 16

Some angles are shown. Complete each of the 2 activities for this Task. Activity 1 of 2 The measure of angle NOP is 140°. Which
garik1379 [7]

Answer:

A. 23+x=140

Step-by-step explanation:

The angle addition postulate states that the measure of a larger angle formed by two or more smaller angles placed side by side is the the sum of the smaller angles. The angle addition postulate states that if B is in the interior of AOC , then:

m∠AOB + m∠BOC = m∠AOC.

From the image:

∠NOP = ∠NOQ + ∠QOP

∠NOP = 140, ∠NOQ = x, ∠QOP = 23

substituting:

140 = x + 23

x = 140 - 23 = 117

∠NOQ = 117°
