The surface area of the solid shape is the amount of space on it
The radius of the two cones is 2.93 cm
<h3>How to determine the radius?</h3>
The given parameters are:
- Cone 1: slant height, l = 2r
- Cone 2: slant height, L = 3r
- Surface area = 135. 21 cm²
The surface area of the shape is calculated using:
T = πr(L + l)
So, we have:
135.21 = πr(2r + 3r)
Evaluate
135.21 = 5πr²
Divide both sides by 5π
r² = 135.21/5π
Evaluate the quotient
r² = 8.61
Take the square root of both sides
r = 2.93
Hence, the radius of the cones is 2.93 cm

ndex Notation and Powers of 10
10 to the Power 2
The exponent (or index or power) of a number says
how many times to use the number in a multiplication.
102 means 10 × 10 = 100
(It says 10 is used 2 times in the multiplication)
Example: 103 = 10 × 10 × 10 = 1,000
In words: 103 could be called "10 to the third power", "10 to the power 3" or simply "10 cubed"
Example: 104 = 10 × 10 × 10 × 10 = 10,000
In words: 104 could be called "10 to the fourth power", "10 to the power 4" or "10 to the 4"
Answer:
-38.4
Step-by-step explanation:
Multiply both sides by 6 to get rid of the /6 then you would get z alone
