Answer:
1+1
Step-by-step explanation:
B. 2
1 is way too big, 4 is way too small, 3 is clearly less than a fourth of the pie chart, so it must be 2.
Answer:
294cm²
Step-by-step explanation:
Given the formula for surface area expressed as 6L^2
TSA = 6L²
Given that L = 7cm
Substitute
TSA = 6(7)²
TSA = 6 * 49
TSA = 294cm²
<em>Hence the total surface area is 294cm²</em>
The LCM for 20 and 30 is 60 because 20 times 3 equals 60 and 30 times 2 is 60
